The full ingredients list is: Aqua (Water), Alcohol denat, VP/VA Copolymer, Acacia senegal gum, Capryloyl glycine, Xanthan gum, Caffeine, Butylene glycol, Parfum (Fragrance), Dextran, Glycerin, Sodium hyaluronate Crosspolymer, Urea, Disodium phosphate, Acetyl Hexapeptide-1, Acetyl Tetrapeptide-3, Trifolium Pratense (Clover) Flower Extract, Sodium chloride, Alcohol, Olea Europaea Fruit Extract, Biotin, Citronellol, Limonene, Citric acid, Linalool, Cytidine, Monophosphate, Disodium Uridine Phosphate, Adenosine Phosphate. **Q: Can this be used in men?** A: The product contains active ingredients that are beneficial to both men and women. However, the formulation has been optimised for the unique needs of women, which includes catering for longer hair types and a higher proportion of cases involving hair breakage. **Q: Can i still dye my grey hair which is pnly at the front.** A: Yes, ThickTails serum is 100% colour safe. And fine to use with colourants and hair dyes. The serum also contains a natural ingredient to stimulate melanin production in the hair, meaning that hair dyes and colourants will last longer... and you can go longer between hair colouring sessions. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing *by on Reviewed in the United Kingdom 30 March 2024* Makes my hair thicker, with more volume. Smells lovely! It lasts a long time!! ### ⭐⭐⭐⭐ This product seems promising. *by on Reviewed in the United Kingdom 10 February 2021* It is easy to use and has a nice smell. It doesn't have a sticky residue and combs through my hair well. It isn't a very big quantity and so with continued use, it could work out a little pricey. I would recommend it . ### ⭐⭐⭐⭐⭐ Good *by on Reviewed in the United Kingdom 29 June 2026* Been using for couple years ## Frequently Bought Together - ThickTails Root Stimulating Leave-In Hair Serum – 3.4 fl.oz | Strengthens, Nourishes & Revitalises for Fuller-Looking Hair | Caffeine, Biotin & Peptides | Reduce Breakage & Thinning - ThickTails Instant Hair Thickening Spray for Women & Men | Boosts Volume, Fuller-Looking Hair in Seconds | Sulphate-Free, Caffeine & Keratin Infused Pre-Styler | Lightweight, No Residue, 3.4 fl.oz - Hair Growth Vitamins for Women with Biotin, Collagen Peptides, Vitamin C & Omega-3 – 90 Capsules – Hair Supplements for Menopause & Postpartum – Hormonal Balance Support & Thicker Hair for Women --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/121287403-thicktails-hair-growth-serum-for-women-caffeine-biotin-and-peptides](https://www.desertcart.jp/products/121287403-thicktails-hair-growth-serum-for-women-caffeine-biotin-and-peptides) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-01*
