What is Dercos Aminexil?
Dercos Aminexil is a topical Hair Loss Shampoo treatment by Vichy that contains aminexil, a molecule designed to prevent collagen hardening around the hair root. It is commonly used to combat hereditary and stress-related hair thinning. A 2013 double-blind study published in the Journal of the European Academy of Dermatology and Venereology showed aminexil reduced hair shedding by 8% more than placebo over six months.
You might have stumbled on this name while frantically Googling at 2 a.m. with a newborn in one arm and a clump of Urban Care Expert Hair in the other. Postpartum shedding hits hard, usually around three to four months after delivery. Your estrogen levels crash, and up to 50% of your hair can enter the resting phase at once. It is normal, but that doesn't make it any less jarring.
Dercos Aminexil comes in single-dose glass ampoules. Each box contains 12 or 18 ampoules, each with 1.5% aminexil plus vitamins B3, B5, and B6. The liquid feels watery, not greasy. You snap open the ampoule, attach the applicator tip, and massage it directly onto a dry or towel-dried scalp every day. No rinsing required. A month's supply runs about $30 to $40 if you source it from Turkey, compared to $55 or more at European pharmacies.
How does aminexil actually work?
Hair follicles sit inside a collagen-rich sheath. Over time, or under hormonal stress, that collagen can stiffen and squeeze the follicle, reducing blood flow and nutrient delivery. Aminexil is thought to keep the collagen around the root flexible. Think of it like loosening a tight collar so the follicle can breathe. The molecule is structurally similar to minoxidil but works through a different mechanism, one that targets fibrosis rather than vasodilation.
According to the 2013 clinical trial, 130 men with androgenetic alopecia applied either aminexil or a placebo daily. After six months, the aminexil group had significantly fewer hairs in the telogen (shedding) phase and a higher anagen-to-telogen ratio. The difference was modest but measurable. For postpartum hair loss, which is typically telogen effluvium, keeping follicles in the growing phase longer can make a visible difference as your body resets.

Nourkrin Woman: a different approach
While aminexil works topically, Hair Health and Growth: Addressing Concerns from Alopecia to Bond Repair goes the oral route. Its star ingredient is Marilex, a proprietary extract of fish cartilage and marine proteins. The logic: hair is made of protein, so feeding it the right building blocks can normalize the hair growth cycle. Each tablet contains 600 mg of Marilex, plus Dermoskin Biotin Men's Shampoo and silica. A 60-tablet box costs around $50 and lasts one month at the recommended dose of two tablets daily.
Targeting Hair Concerns: Solutions for Growth and Scalp Health is often marketed specifically for women with diffuse thinning, including postpartum shedding. A 2014 observational study on 55 women with telogen effluvium found that after six months of Nourkrin, 83% reported reduced hair loss and improved hair density. The study was funded by the manufacturer, so take the numbers with a grain of salt, but the mechanism (providing proteoglycans that support the follicle's anagen phase) aligns with what we know about hair biology.
The catch: you must be consistent. Missing days blunts the effect. And if your hair loss is driven by iron deficiency or thyroid issues, no amount of marine protein will fix it. A blood panel from your doctor costs less than a year's supply of supplements and can save you months of frustration.
Alopecia shampoos: what to look for
An "alopecia shampoo" is not a regulated term. It is a catch-all for shampoos that claim to reduce shedding, thicken strands, or stimulate the scalp. Most contain one or more of these ingredients: ketoconazole, salicylic acid, biotin, caffeine, or saw palmetto. Ketoconazole, a 1% antifungal, has the strongest evidence. A 1998 study in the journal Dermatology showed that 2% ketoconazole shampoo increased hair density and the size of hair shafts in men with androgenetic alopecia, comparable to 2% minoxidil.
For postpartum thinning, a gentle, sulfate-free shampoo with biotin and panthenol can help preserve the hair you have while new growth comes in. Avoid harsh clarifying shampoos that strip the scalp; dry, inflamed skin sheds more. If you see "alopecia shampoo" on a label, flip it over and check for ketoconazole or at least caffeine. Without those, you're paying for fancy-scented soap.
Head and Shoulders Clinical Strength: more than dandruff
Head and Shoulders Clinical Strength contains 1% selenium sulfide, an anti-fungal that also reduces scalp inflammation. Itchy, flaky scalps can accelerate shedding because scratching damages follicles. A healthy scalp environment is non-negotiable for regrowth. The American Academy of Dermatology notes that treating seborrheic dermatitis, a common cause of scalp flaking, can reduce hair loss associated with inflammation.
This shampoo is not a hair growth treatment per se, but if your postpartum shedding is compounded by a stressed, oily scalp, using it twice a week can calm things down. The bottle costs about $10 at most drugstores. It lathers into a dense foam and should sit on the scalp for two to three minutes before rinsing. Pair it with a lightweight conditioner on the ends only, otherwise the zinc can leave hair feeling straw-like.
Glycolic acid for the scalp: why it works
Glycolic acid is an alpha-hydroxy acid (AHA) that exfoliates dead skin cells. Your scalp regenerates cells just like your face, and buildup of dead skin can clog follicles and trap oil. A 5% to 10% glycolic acid serum applied before washing can clear that debris. It also lowers the scalp's pH, which may discourage fungal overgrowth. In a small 2020 study in the International Journal of Trichology, a 10% glycolic acid scalp peel improved hair density in women with androgenetic alopecia after 12 weeks when used weekly.
For a new parent, this is a low-effort add-on. Apply the serum along your part lines, massage for 30 seconds, wait 10 minutes, then shampoo. Do it once a week. The Ordinary's Glycolic Acid 7% Toning Solution costs under $10 and works for both face and scalp. Avoid higher concentrations without a dermatologist's guidance; 20% or more can cause chemical burns on a postpartum scalp that is already sensitive.
Comparing your options side by side
Each approach targets a different piece of the hair loss puzzle. The table below lays out the core differences so you can see what fits your routine and budget.
| Product | Key Ingredient | How It Works | Best For | Price Range (Monthly) | Notes |
|---|---|---|---|---|---|
| Dercos Aminexil | 1.5% Aminexil | Prevents collagen hardening around follicles | Early-stage thinning, telogen effluvium | $30-$40 | Topical ampoules, no rinse |
| Nourkrin Woman | Marilex (marine proteins) | Provides proteoglycans to normalize hair cycle | Diffuse shedding, postpartum | $50 | Oral tablets, 2/day |
| Head & Shoulders Clinical Strength | 1% Selenium sulfide | Reduces scalp inflammation and flaking | Scalp-driven shedding, dandruff | $10 | Shampoo, use 2x/week |
| Glycolic Acid Scalp Serum | 5-10% Glycolic acid | Exfoliates dead skin, clears follicles | Buildup, oily scalp, clogged follicles | $10 | Pre-shampoo treatment, 1x/week |
| Ketoconazole Shampoo | 1% Ketoconazole | Antifungal, mild anti-androgen effect | Androgenetic alopecia, inflammation | $15-$25 | Available OTC, leave on 3-5 min |
None of these are overnight fixes. Hair grows about half an inch per month. You need at least three to six months of consistent use before judging results. Taking progress photos in the same lighting every four weeks helps you spot changes your eyes might miss day to day.
Internal support matters just as much as what you put on your scalp. Many Turkish pharmacies stock high-potency biotin, collagen, and herbal blends at a fraction of US prices. Our Turkish supplements collection includes options that may complement your topical routine without breaking the bank.
Putting it all together: a simple routine
If you are juggling a baby and a dwindling ponytail, keep things simple. A morning routine might look like: apply Dercos Aminexil ampoule to dry scalp, no rinse. At night, wash with a ketoconazole or selenium sulfide shampoo twice a week, using a gentle biotin shampoo on other days. Once a week, do a glycolic acid scalp treatment before washing. Take Nourkrin tablets with breakfast if you choose the oral route. And get your ferritin and thyroid levels checked; fixing a deficiency can do more than any serum.
A note on safety while breastfeeding
Topical aminexil is not known to be absorbed systemically in significant amounts, but there is no solid safety data during lactation. The same goes for most hair loss actives. Many dermatologists advise sticking to mechanical and nutritional support (gentle massage, biotin, iron if needed) until you finish breastfeeding. Always run any product by your own doctor. What works for one mom may not be right for your unique situation.
