The Treatment Scalp Serum | Hair Growth Serum for Thinning Hair | KilgourMD

In laboratory (in vitro) studies, Redensyl-treated follicles showed a 200% increase in thickness, compared to untreated follicles. This patented complex features a unique combination of molecules that help support the look of thicker, denser hair over time, especially in areas where hair may appear visibly thinner. By helping maintain a balanced, well-cared-for scalp environment, it supports hair that looks fuller, stronger, and more vibrant—without irritation.

A well-established, natural suppressor of 5α reductase—the enzyme that converts testosterone into DHT, the main driver of follicle miniaturization. Clinical reviews have shown that Saw Palmetto can reduce androgen receptor activity in the scalp by 50%, and it is linked to reduced hair shedding and increased hair thickness without systemic side effects.

Rosemary extract has demonstrated strong scalp-soothing and antioxidant effects, particularly beneficial for scalp health. A 2020 review highlighted that rosemary improves local scalp circulation, soothes irritation, and may be as effective as leading hair loss alternatives in improving hair count. Its use has been associated with reduced scalp itchiness, decreased visible flakes, and improved follicular environment.

Contains ginsenosides, bioactive compounds known to stimulate hair follicles, promote proliferation, and reduce surface inflammation. A 2020 review outlined its use in herbal hair loss treatments, citing improved follicular strength, hair shaft thickness, and overall scalp health. Ginseng also supports microcirculatory flow locally in the scalp, enhancing nutrient delivery while calming stress responses tied to thinning and flaking.

Rich in antioxidants and vitamin C, offering significant protective and regenerative benefits for the scalp. A 2020 clinical study evaluated a hair serum containing amla over 90 days. Results showed a notable increase in hair growth rate, density, and reduced hair fall. The serum was well tolerated, with no adverse events, and demonstrated strong support for healthier, more resilient hair. Amla's high antioxidant content helps counter oxidative stress at the local follicular level, preserving hair integrity and supporting rejuvenation.

Contains phytosterols, zinc, and omega fatty acids that naturally supress 5α reductase, the enzyme responsible for converting testosterone to DHT. A 2014 study demonstrated a 40% increase in hair count and 30% improvement in hair thickness after 24 weeks of use. The extract also provides essential minerals that support keratin production, while its scalp anti-inflammatory properties help maintain optimal pH and reduce environmental oxidative stress linked to follicle miniaturization.

Penetrates around the hair follicles following topical application, where it supresses DHT effects and supports cellular metabolism. This powerful ingredient extends the anagen (growth) phase by 37% and increases hair shaft elongation by 46%. It enhances local ATP production in follicular cells, counteracts testosterone-induced follicle suppression, and improves barrier function. Unlike systemic caffeine intake, topical application delivers therapeutic doses locally to follicles without side effects.

A potent antioxidant and scalp anti-inflammatory compound shown to support microcirculation and neutralize free radicals in scalp tissue. It helps protect follicular DNA from oxidative damage, which is especially relevant during menopause when antioxidant production declines. Pine Bark (notably as Pycnogenol®) has shown strong antioxidant effects in skin studies and is commonly used to reduce oxidative aging and scalp inflammation—both of which are known contributors to follicle aging and hair loss.

Turmeric's active compound, curcumin, is a potent natural scalp anti-inflammatory shown to suppress 5α reductase and local inflammatory cytokines. In hair loss contexts, it has been studied for its role in soothing scalp inflammation, balancing microbiota, and reducing oxidative stress. A 2020 systematic review emphasised turmeric's ability to address local hormonal and inflammatory triggers of alopecia while enhancing follicle resilience in stressed scalps.
