grow hair bundle

What makes the product special

Shiny, healthy, voluminous hair and no more hair loss – sounds good, right?

Hair loss in women can be driven by an increased sensitivity of the hair follicles to DHT. DHT is a by-product of testosterone metabolism and is a major contributor to hormonally driven hair loss in both women and men. Elevated testosterone levels can occur, for example, after stopping hormonal contraception or during periods of prolonged stress.

With the grow hair bundle, you get optimised care for hair and scalp, plus targeted support for the hair follicles against DHT.

grow hair serum contains a unique active complex with red clover, which has been shown in studies to help inhibit the conversion of testosterone to DHT. Hair loss may be reduced, hair growth and collagen synthesis stimulated, and hair count, density and anchoring increased. With plant extracts that may act on oestrogen receptors, grow hair serum supports you daily in managing hair loss.

grow shampoo not only nourishes and protects your hair, but also contains a combination of plant extracts that have shown DHT-reducing effects in studies.

Hair loss is a thing of the past with your new optimised haircare routine from fenou!

High-quality active ingredients for your health

Developed with experts from the fields of gynecology, naturopathy and nutritional science. The selected ingredients are based on the latest scientific findings.

  • Compounds from Urtica dioica (nettles) influence the expression of the gene for 5-alpha-reductase and may potentially inhibit the conversion of androgens into DHT. This can help reduce androgen-related hair loss.

  • Saw palmetto fruit extract is derived from the fruits of the saw palmetto (Serenoa repens). It is naturally rich in phytosterols.

  • Rosemary is commonly used in products that support hair health, especially in formulas designed to have an “energising” or “revitalising” effect. Rosemary has antispasmodic properties that may also influence the vascular smooth muscle in the scalp, potentially improving blood flow to the hair follicles. In addition, rosemary has antioxidant effects, which may counteract hair loss caused by oxidative stress. Rosemary also has antibacterial and antifungal properties, helping to nourish and care for both scalp and hair, resulting in soft, shiny hair.

  • AC Vegan Kerazyme Protect is an active complex based on bamboo, plant-derived keratin, and extracts from the butterfly tramete mushroom. AC Vegan Kerazyme Protect helps protect the hair from heat and UV damage and reduces UV-related colour fading.

  • Hydrolite 5 green is sustainably derived from renewable sugarcane. It provides moisture to the scalp and enhances the effectiveness of the other active ingredients.

  • Aloe vera has been shown in studies to enhance the absorption of pharmacologically active substances through the skin by increasing skin permeability. It is also thought that aloe vera may support hair growth due to its content of aloenin and its high levels of B vitamins.

  • Rosemary is commonly used in hair-care products, especially those intended to feel “revitalising” or “invigorating”. Rosemary has a relaxing effect on smooth muscle tissue and may therefore influence the vascular muscles in the scalp, supporting blood flow to the hair follicles. In addition, rosemary offers antioxidant properties that may help counter hair loss linked to oxidative stress. Rosemary also has antibacterial and antifungal effects, helps nourish the scalp and hair, and can promote smooth, shiny hair.

  • Inutec H25P is an inulin formulation derived from plant-based inulin sourced from chicory root. It helps make the hair feel softer and look shinier.

  • D-Panthenol acts as a provitamin of pantothenic acid (vitamin B5) and works directly on cellular growth within the hair follicles. In this way, D-panthenol may help support healthy hair growth.

  • Green tea (Camellia sinensis) is rich in the non-proteinogenic amino acid L-theanine. The extract we use contains 60% L-theanine.

  • Chamomile flower extract contains the flavonoid apigenin. Apigenin is considered one of the key compounds responsible for chamomile’s anti-inflammatory and antibacterial properties, contributing to its calming effect on the skin.

  • Horsetail has shown 5-alpha-reductase-inhibiting effects in studies and may therefore help with androgen-related hair loss. It also supports hair growth through its anti-inflammatory and antioxidant effects on the scalp.

  • “I’ve been using Fenou’s Grow Hair Serum regularly for some time now (about every two days) and I’m very positively surprised. During this period, my hair has genuinely become longer and stronger again — even alongside supplements. What I particularly like is how ultra-light the serum feels on the scalp; it doesn’t weigh the hair down, doesn’t make it sticky, and leaves no greasy residue at all. The application is straightforward, the scent subtle, and the results really convince me. For anyone looking to support hair length and hair health: an absolute recommendation!”

    Peggy

  • “I’ve been using the duo for two weeks now and my hair is slowly recovering — I’m no longer losing as much hair as before. Applying the serum to a clean scalp is all it takes. The shampoo cleanses my hair gently and makes it feel stronger. You can really tell that it’s full of the goodness of nature.”

    Yvonne

  • “I’ve been using it for a long time — I stopped using the serum for a while and the hair loss immediately came back. I can also recommend the shampoo to anyone with straight hair that gets greasy quickly. It doesn’t weigh the hair down and smells wonderful. Even with daily washing, one bottle lasts me three months.”

WHAT TO DO ABOUT HAIR LOSS? HOW GROW CAN SUPPORT YOU

Hair loss in women can have multiple causes. One underlying factor is an elevated androgen level, which may be triggered by chronic stress, occur as a result of underlying conditions such as PCOS, or develop after stopping the oral contraceptive pill due to an androgen rebound. In addition, androgenetic alopecia is a condition in which hair follicles are hypersensitive to androgen by-products. In about one third of cases, this also occurs alongside elevated androgen levels. In all of these situations, the formation of DHT from androgens at the hair follicle level leads to follicle dysfunction (miniaturisation).

For the development of the grow products, we collaborated with medical doctors and experts in natural cosmetics, hair care and plant-based actives. Through an extended development process, we created formulations tailored to the needs of hormonally driven hair loss. Both products contain plant actives shown in studies to inhibit 5-alpha-reductase, the enzyme responsible for converting androgens into DHT at the follicle site. So what can you do about hair loss? Address the cause directly at the follicle level. grow products are designed to act locally at the site where hair loss begins. In clinical studies, Capixyl™ achieved reduced hair loss, stimulated hair growth, increased hair number and density, supported collagen synthesis and improved follicle anchoring.

WHY SHOULD I COMBINE GROW PRODUCTS?

Using grow Hair Serum and grow Shampoo together is especially beneficial. Thanks to its water-based texture, the serum remains on the scalp without weighing down the hair. Plant actives such as Capixyl™ can act directly in the surrounding follicular tissue. Ideally, massage the serum into affected areas with a scalp massage brush to support circulation through the rosemary extract it contains. You can apply the serum daily, or at least 3 times per week, on dry or damp scalp. The perfect complement to this is grow Shampoo, which contains a particularly mild surfactant blend to protect hair and scalp. It also delivers plant actives that support microcirculation and have shown effects on androgen metabolism (reducing DHT formation) and on oestrogen receptors in studies. Plant-derived keratin helps protect hair from environmental damage. So what to do about hair loss? Build your routine around the grow bundle.

HOW CAN GROW SUPPORT ME AFTER STOPPING THE PILL?

The pill suppresses the body’s natural production of androgens and oestrogens. After stopping, the supply of synthetic hormones ends abruptly, and an oestrogen deficit may develop in the first weeks or months. About three months later, an androgen rebound may occur. This is an overactive androgen production response. Elevated DHT levels shorten the hair growth phase and damage the follicle structure, eventually leading to hair loss and thinning. The active ingredients in grow Hair Serum and grow Shampoo aim to counteract this process while supporting healthy scalp and hair care. The grow bundle is the answer to the question: “What can I do about hair loss after stopping the pill?”

CAN I USE GROW PRODUCTS FOR HAIR LOSS CAUSED BY PCOS OR ANDROGENETIC ALOPECIA?

Polycystic ovary syndrome (PCOS) can lead to elevated androgen levels, causing symptoms such as hair loss, hirsutism and acne. In these cases, hair loss may result from follicle sensitivity to DHT. In androgenetic alopecia, follicles are genetically predisposed to respond to DHT. Active ingredients such as Capixyl™ or saw palmetto may act as plant-derived 5-alpha-reductase inhibitors and help reduce DHT levels. However, use in PCOS or androgenetic alopecia should always be discussed with your healthcare professional.
