Hair thinning doesn't happen overnight. Neither does addressing it. You need a daily treatment shampoo formulated around the science of DHT.

Pattern hair thinning is one of the most common and most quietly distressing hair concerns that people face. It progresses gradually: the hair growth cycle shortens, strands become finer, the scalp becomes more visible, and the density that once felt effortless starts to feel like something being lost. By the time it is clearly noticeable, the process has often been underway for years.

The cause, in most cases, is DHT (dihydrotestosterone), a hormone that binds to androgen receptors in susceptible hair follicles and gradually miniaturises them. Addressing it requires more than a nutritious shampoo. It requires an active that targets the enzyme driving DHT production at the scalp, and one that supports the structural proteins that keep the follicle anchored and productive.

The BioScalp DHTI Control Shampoo is built around Capixyl™ - a patented peptide complex that does exactly that. Used daily as Step 2 in the BioScalp 3-step system, it is the treatment-grade shampoo for anyone who wants to take a serious, proactive approach to thinning hair from the root up.

Hear what people say

DHTI Control Shampoo works best in a 3-step routine

Capixyl™ works during the wash. The steps before and after determine how well it can reach the scalp — and how long the benefits last.

  • Step 1 - Pre-cleanse: Use the BioScalp Scalp Cleanser to lift away buildup and excess sebum before shampooing, so Capixyl™ can work on a clear, unobstructed scalp surface rather than through a layer of residue.
  • Step 2 - Treat: Use BioScalp DHTI Control Shampoo to deliver Capixyl™ to the follicle, target DHT production, and support stronger hair anchoring during every wash.
  • Step 3 - Sustain: Use the BioScalp Advanced Scalp Tonic as a daily leave-in to extend the treatment window, delivering Capixyl™, Biotin, Ginseng, and amino acids to the follicle throughout the day, not just at wash time.

Who This Is For

The BioScalp DHTI Control Shampoo is designed for anyone experiencing early to moderate signs of hormonal or hereditary hair thinning and wanting to incorporate a targeted daily treatment into their routine. It is particularly suited to:

  • Hair that has become noticeably finer, weaker, or less dense over time
  • A widening part, a thinning crown, or a hairline that has begun to recede gradually
  • Increased daily hair fall - more strands than usual in the shower, on the pillow, or in the brush
  • Those with a family history of pattern hair loss who want to take a preventative approach
  • Anyone who has experienced thinning linked to hormonal changes, stress, or post-partum hair fall
  • Those seeking a daily-use treatment shampoo that is SLS-free and gentle on sensitive scalps

Why Most Shampoos Cannot Address Hair Thinning

Standard shampoos, even those marketed for thinning hair, are primarily designed to cleanse. They may include biotin, keratin, or volumising agents to improve the look and feel of thinning hair, but they do not address the hormonal process driving it.

Reversing or slowing DHT-related thinning requires an active ingredient that can interact with the 5-alpha-reductase enzyme at the scalp level, the enzyme responsible for converting testosterone into DHT, and that can support the structural environment of the follicle. Without this, a "thinning hair" shampoo is largely addressing the appearance of the problem rather than the cause.

Capixyl™, the core active in this shampoo, is formulated specifically to do both: inhibit the enzymatic driver of DHT production, and stimulate the proteins that structurally anchor the hair bulb. This is what makes the DHTI Control Shampoo a treatment product rather than simply a cosmetic one.

How It Works

  • Capixyl™ (Acetyl Tetrapeptide-3 + Red Clover/Trifolium pratense Extract): The hero active in this formula. Capixyl™ is a patented biomimetic peptide complex developed for scalp and follicle care. Acetyl Tetrapeptide-3 stimulates the production of key extracellular matrix proteins, including collagen IV and laminin-5, that form the structural anchoring around the hair bulb, helping to keep hair more firmly rooted and reducing the fragility that leads to increased shedding. Red Clover Extract, rich in biochanin A, helps inhibit 5-alpha-reductase at the scalp surface, targeting the enzyme that drives the DHT conversion responsible for follicle miniaturisation. Together, these two components address thinning from the hormonal and structural sides simultaneously.
  • Salicylic Acid: Provides gentle scalp exfoliation to keep follicle openings clear of excess sebum and dead skin, ensuring Capixyl™ can reach the scalp surface without obstruction during the wash, and that the follicle environment is not congested between washes.
  • Aloe Vera (Aloe barbadensis leaf extract): Soothes and hydrates the scalp during the treatment wash, calming any sensitivity or tightness and ensuring the shampoo is comfortable enough for daily use even on reactive scalps.
  • Pro-Vitamin B5 (Panthenol): Conditions and strengthens the hair shaft alongside the scalp treatment, leaving hair softer, more manageable, and less prone to breakage at the lengths, which contributes to the perception of improved density.
  • Dextran: A skin-conditioning polysaccharide that supports hydration and helps the formula feel smooth and nourishing on both scalp and hair during use.
  • Gentle coconut-derived surfactants: A mild, SLS-free cleansing base that removes oil and product buildup effectively without stripping the scalp, preserving the natural moisture barrier that a healthy follicle environment depends on.

Key Ingredients

  • Capixyl™ (Acetyl Tetrapeptide-3 + Red Clover Extract): patented DHT-inhibiting peptide complex, follicle anchoring support
  • Salicylic Acid: scalp exfoliation, follicle clarity
  • Aloe Vera: soothing scalp hydration
  • Pro-Vitamin B5 (Panthenol): conditioning, hair strength
  • Dextran: skin conditioning and hydration support
  • Coconut-derived surfactants: gentle, effective cleansing

Free from SLS, SLES, and parabens. Suitable for daily use on all scalp types, including sensitive, reactive, and colour-treated hair.

The BioScalp Routine

The DHTI Control Shampoo delivers its best results as Step 2 in the complete BioScalp 3-step system. The shampoo is a two-minute contact window, and the steps before and after it determine how much of that time is actually spent working on a clear, receptive scalp.

  • Step 1 - Scalp Cleanser: Lifts away the layer of excess sebum, dead skin, and product residue that accumulates at the scalp between washes. By clearing this barrier before shampooing, Capixyl™ can reach the follicle surface without obstruction, working on a primed scalp rather than through buildup.
  • Step 2 - DHTI Control Shampoo (this product): Delivers Capixyl™ to the scalp to target DHT production and support follicle anchoring, while gently cleansing and conditioning the scalp and hair.
  • Step 3 - Advanced Scalp Tonic: Applied as a daily leave-in after washing, the Tonic extends the treatment window from two minutes to the rest of the day, delivering Capixyl™, Ginseng, Biotin, amino acids, and Niacinamide to the follicle environment continuously between washes.

Want all three steps together? The BioScalp DHTI Control Kit includes the Cleanser, this shampoo, and the Advanced Scalp Tonic, everything needed for the complete routine, at a saving.

For best results, aim to complete the bottle within 30 days of opening and use consistently as part of your daily wash routine.

How to Use

  1. For best results, begin with the BioScalp Scalp Cleanser on a wet scalp. Massage in and rinse thoroughly.
  2. Apply the DHTI Control Shampoo directly to the scalp and work through the lengths.
  3. Massage gently in circular motions - a silicone scalp brush improves product distribution and scalp contact without abrasion.
  4. Leave briefly to allow Capixyl™ to work, then rinse thoroughly.
  5. Follow with conditioner on the lengths if needed.
  6. Finish with the BioScalp Advanced Scalp Tonic applied to a towel-dried scalp. Do not rinse.

What a targeted, daily routine feels like

From fragile and thinning to nourished and stronger at the root

Before: hair that feels finer and more fragile than it used to, more strands than usual coming out during washing and styling, and the quiet worry that comes with noticing your scalp through your hair more often. After: a scalp that feels genuinely cared for and nourished, hair that feels less fragile at the root, and a daily routine that addresses the cause rather than just the appearance. Visible changes in density and hair feel are gradual. Most customers notice scalp comfort and reduced shedding during washing first, with changes in appearance building with consistent use over weeks.

Did You Know

Most people lose between 50 and 100 hairs per day as part of the normal growth cycle, so increased shedding alone is not necessarily a sign of pattern thinning. The key indicator is whether the hairs being shed are being replaced by hairs of the same calibre, or by progressively finer, shorter strands. When DHT is driving follicle miniaturisation, the replacement hairs become thinner and shorter with each cycle, producing the gradual loss of density and coverage that characterises androgenetic alopecia. Capixyl™ is designed to intervene in that process: the Red Clover Extract component targets the enzyme driving DHT conversion, while Acetyl Tetrapeptide-3 supports the proteins that keep the follicle structurally anchored and productive. The earlier this intervention begins in the thinning process, the more follicle function there is to preserve.

    Tackles the cause

    Capixyl™ targets 5-alpha-reductase, the enzyme at the scalp that converts testosterone into DHT, via the biochanin A-rich Red Clover Extract component. This is not a cosmetic fix for the appearance of thinning hair; it is a targeted approach to the hormonal mechanism driving it, delivered daily through a gentle treatment shampoo.

  • water drop line graphic, light pink circle background
    Fortifying hair roots

    Acetyl Tetrapeptide-3, the peptide component of Capixyl™, has been shown to stimulate collagen IV and laminin-5 - key structural proteins that physically anchor the hair bulb within the follicle. Stronger anchoring means less shedding during washing and styling, and a follicle that remains productive for longer.

  • line drawing of hair follicle, blue circle background
    Strength from root to tip

    While Capixyl™ works at the scalp, Pro-Vitamin B5 and Dextran condition and strengthen the hair shaft itself, improving softness, manageability, and resilience at the lengths. The result is a shampoo that treats the scalp concern and improves the visible quality of the hair simultaneously, without compromise.

Defend against hormonal hair thinning

Block DHT, Boost Growth

DHT (dihydrotestosterone) is the primary hormonal driver of the most common form of pattern hair loss in both men and women. It acts by binding to androgen receptors in susceptible follicles, gradually shortening the active growth phase and miniaturising the follicle over successive cycles. The Red Clover Extract in Capixyl™, rich in biochanin A, targets 5-alpha-reductase, the enzyme responsible for DHT production at the scalp, helping to slow the miniaturisation process at its enzymatic source. Used daily, it provides a consistent, topically delivered intervention against the hormonal signal that drives pattern thinning and the earlier it is incorporated into a routine, the more follicle function there is to work with.

Capixyl™

Capixyl™ is the most clinically validated active in this formula, and the reason this shampoo occupies a different category from standard thinning-hair shampoos. The Acetyl Tetrapeptide-3 component works by stimulating the synthesis of collagen IV and laminin-5 in the basement membrane surrounding the hair bulb - the structural proteins responsible for physically anchoring the follicle and maintaining its productive capacity. When these proteins are depleted, the follicle loses its mechanical hold on the hair shaft, increasing shedding and shortening the growth cycle. By supporting their production, Capixyl™ helps maintain the structural integrity of the follicle from the inside out, working alongside the DHT-inhibiting Red Clover Extract to address thinning from both the hormonal and structural angles.

Healthy Scalp, Healthy Hair

Capixyl™ is most effective when it can reach the scalp unobstructed, which is why the DHTI Control Shampoo works best as part of the complete BioScalp 3-step system. The Scalp Cleanser removes the layer of sebum, dead skin, and product residue that accumulates between washes and limits how effectively treatment actives can penetrate. The Advanced Scalp Tonic then extends the treatment window throughout the day, delivering Capixyl™, Biotin, Ginseng, and amino acids to the follicle environment continuously after the wash. The shampoo is the core treatment; the system is what makes it consistently effective.

Don't take our word for it

I’ve struggled with thinning along my crown for over a year. After just around 6 weeks using BioScalp DHTI Control Shampoo (as part of the kit), I noticed significantly less hair loss in the shower. The scalp feels more balanced and less oily too, and my hair now looks fuller at the top.

Emmanuel, 32, Sydney

My scalp used to be oily and prone to breakouts, especially after workouts. This shampoo gently cleanses without dryness and seems to control oil build‑up. It also reduced irritation and scaliness after a few uses. Rather than stripping, it leaves the scalp feeling balanced. Over time my hair feels thicker and healthier.

Meagan, 41, Gold Coast

I used this mainly as part of the DHTI Control Kit to tackle early signs of hair thinning. After about eight weeks, my parting line looked noticeably denser and there was less hair in the drain. It’s not a miracle solution, but for early-stage thinning and hormonal hair loss, it’s been a solid, science‑backed addition to my routine.

James, 39, Townsville

Dihydrotestosterone (DHT) is a hormone derived from testosterone that plays a complex role in hair growth. While it contributes to body and facial hair development, it is also a key factor in androgenetic alopecia (pattern hair loss).

In individuals genetically sensitive to DHT, it binds to hair follicle receptors on the scalp, causing follicular miniaturisation. This process shortens the hair growth cycle, leading to thinner, weaker strands until the follicles eventually stop producing hair. Over time, this results in hair thinning and balding, especially in men.

DHT blockers, such as prescribed medication or natural ingredients like saw palmetto, can help reduce its effects and slow hair loss. However, DHT does not affect all hair follicles equally. It primarily impacts scalp hair while stimulating growth in other areas, like the beard.

Hereditary hair thinning, also known as androgenetic alopecia, is closely linked to dihydrotestosterone (DHT), a byproduct of testosterone. In individuals with a genetic predisposition, DHT binds to hair follicle receptors on the scalp, causing them to shrink over time. This miniaturization shortens the hair growth cycle, leading to thinner, weaker hair until follicles stop producing new strands altogether.

Hormonal scalp concerns, such as excess sebum production or scalp inflammation, can also be influenced by DHT. High DHT levels may overstimulate sebaceous glands, making the scalp oilier and more prone to dandruff or irritation. This can further weaken hair follicles, accelerating hair loss.

Managing DHT-related hair thinning often involves using DHT blockers like prescribed medication or natural inhibitors like saw palmetto, along with scalp treatments to maintain a healthy follicular environment.

Capixyl is an advanced hair growth complex that combines Acetyl Tetrapeptide-3, a bioactive peptide, and Red Clover Extract, which contains Biochanin A, a natural DHT blocker. This innovative formula supports hair roots by strengthening follicles, reducing inflammation, and improving scalp health.

Capixyl works in several ways:

  • DHT Regulation – Biochanin A helps inhibit 5-alpha reductase, the enzyme responsible for converting testosterone into DHT, a key factor in hair thinning.
  • Follicle Strengthening – Acetyl Tetrapeptide-3 stimulates proteins like collagen and laminin, reinforcing the hair root’s structure.
  • Scalp Health – It reduces inflammation and oxidative stress, creating a healthier environment for hair growth.
  • Hair Growth Stimulation – It extends the anagen (growth) phase, promoting thicker, stronger hair over time.

Better anchoring of hair follicles strengthens hair by improving its stability, reducing shedding, and supporting long-term growth. Hair follicles are embedded in the scalp’s dermal papilla, which provides nutrients and signals for healthy hair production. When the follicle’s connection to the scalp is weak—due to inflammation, DHT-related miniaturization, or poor scalp circulation—hair becomes more prone to thinning and premature fallout.

Stronger anchoring ensures that hair remains in the anagen (growth) phase longer, allowing it to grow thicker and healthier before naturally shedding. Ingredients like Acetyl Tetrapeptide-3 (found in Capixyl) and Collagen-boosting peptides help reinforce the follicle’s structure by strengthening the extracellular matrix, which acts as the hair’s foundation. Additionally, a healthy scalp environment with adequate hydration, nutrients, and proper circulation further supports follicle stability, reducing excessive hair loss and promoting stronger, fuller strands over time.

Yes, it’s designed for anyone experiencing hormonal or hereditary thinning, regardless of gender.

Yes, the BioScalp DHTI Control Shampoo is gentle enough for daily use while effectively supporting scalp and hair health.

The BioScalp DHTI Control Shampoo formula targets DHT, one of the key causes of hair loss, and includes Capixyl™ and scalp-soothing actives to strengthen and protect the roots.

No. The BioScalp DHTI Control Shampoo is balanced with panthenol, glycerin, and hair-conditioning agents to leave hair soft, nourished, and manageable.
