{"product_id":"caffeine-growth-shampoo","title":"Caffeine Growth Shampoo","description":"\u003cp class=\"q-lead\"\u003eA caffeine and biotin shampoo for fine or thinning hair, in a 250 mL bottle. A\nshampoo is a rinse-off product, so the honest job it does in a hair loss range is to keep the scalp\nclean, leave the hair with more body once it is dry, and give whatever you apply afterwards a clean\nsurface to sit on. It supports the treatments in this range rather than replacing any of them.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is in it\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eCaffeine.\u003c\/strong\u003e In isolated human follicles kept alive in a dish, caffeine counteracts\nthe growth suppression caused by testosterone, and it raises IGF-1 while lowering TGF-beta2, both of\nwhich are involved in keeping a follicle in its growing phase. That work is ex vivo, done at\nconcentrations well below what a cosmetic uses, and it has never been shown to translate into hair on\na head. There is also imaging work showing that caffeine from a shampoo, massaged in for two\nminutes and rinsed out, does reach the follicle and stays detectable there for up to a day. That\ndemonstrates delivery, and delivery is not the same as an effect.\u003c\/p\u003e\n\u003cp\u003eYou will see caffeine sold on the back of one human trial, which reported a 0.2% caffeine liquid\nas non-inferior to 5% minoxidil solution over six months. It is worth knowing what that trial\nactually was. It was a leave-on liquid applied at 2 mL twice a day, it was open-label by design, it\nwas funded by the company that sells a caffeine shampoo, with a company employee among the authors,\nand it was judged on the proportion of hairs in the growing phase rather than on hair counts or\nphotographs. It also tested caffeine instead of minoxidil, so it says nothing about using both. None\nof it makes caffeine an equivalent to minoxidil, and none of it transfers to a shampoo you rinse\ndown the drain. Caffeine on the scalp remains an unproven ingredient for growth, and minoxidil\nremains the proven one.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBiotin.\u003c\/strong\u003e Biotin is a B vitamin, and it helps hair only in people who are genuinely\ndeficient, which is uncommon on an ordinary diet. The one adequately controlled trial of biotin for\nhair, double-blind and placebo-controlled, found no difference in hair growth. In a shampoo, biotin\nbehaves as a conditioning ingredient, and that is how it is worth thinking about here.\u003c\/p\u003e\n\u003cp\u003eThe word growth in the name describes the shelf this product sits on. The claim that survives\nscrutiny is narrower, and it is about how hair looks and behaves once it is properly clean.\u003c\/p\u003e\n\n\u003ch3\u003eWhy it belongs here\u003c\/h3\u003e\n\u003cp\u003eThis is for men with fine or thinning hair who want a daily wash that cleans the scalp without\nleaving hair flat or coated. Build-up from sebum, styling product and hard water is the most\nunderrated cause of hair looking thinner than it is, and a clean scalp is also the surface a topical\ntreatment works from.\u003c\/p\u003e\n\u003cp\u003eIt is built to run with the \u003ca href=\"\/products\/caffeine-conditioner\"\u003eCaffeine Growth\nConditioner\u003c\/a\u003e, which is the same pairing on the lengths. If you want caffeine on your scalp with\nreal contact time behind it, the \u003ca href=\"\/products\/caffeine-scalp-serum\"\u003eCaffeine Scalp Serum\u003c\/a\u003e\nis the leave-on version, which is the only sensible way to use the ingredient. If your\nactual goal is regrowth, \u003ca href=\"\/products\/minoxidil-topical-solution-5\"\u003eMinoxidil Topical Solution\nUSP, 5%\u003c\/a\u003e is the only thing in this range with strong evidence behind it, and nothing on this page\nsubstitutes for it. If flaking or itch is the problem you are trying to solve, the\n\u003ca href=\"\/products\/anti-dandruff-shampoo\"\u003eAnti-Dandruff Shampoo\u003c\/a\u003e is the right wash instead of this\none, and if you use heavy styling products or scalp oils, the\n\u003ca href=\"\/products\/deep-cleanse-shampoo\"\u003eDeep Cleanse Scalp Shampoo\u003c\/a\u003e once a week clears what a\ndaily wash leaves behind.\u003c\/p\u003e\n\n\u003ch3\u003eHow to use it\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDaily use is fine. Most men will use it three or four times a week, on whichever days\nthey already wash.\u003c\/strong\u003e\u003c\/p\u003e\n\u003col\u003e\n  \u003cli\u003eWet your hair thoroughly with warm water. Hot water leaves the scalp tight and itchy.\u003c\/li\u003e\n  \u003cli\u003eTake about 5 mL, roughly the size of a ten pence piece, into a wet palm. Use twice that only if\n    your hair is past your collar.\u003c\/li\u003e\n  \u003cli\u003eWork it into the scalp with your fingertips, not your nails, and keep going for\n    a full two minutes. Two minutes is the contact time used in the follicle penetration work, and it\n    is far longer than most people spend.\u003c\/li\u003e\n  \u003cli\u003eLeave the lengths alone. The lather running down them as you rinse is enough for hair that is\n    fine to begin with.\u003c\/li\u003e\n  \u003cli\u003eRinse until the water runs completely clear. Surfactant left behind is a common cause of an\n    itchy scalp that then gets blamed on the treatment.\u003c\/li\u003e\n  \u003cli\u003eFollow with the \u003ca href=\"\/products\/caffeine-conditioner\"\u003eCaffeine Growth Conditioner\u003c\/a\u003e on the\n    mid-lengths and ends, keeping it off the scalp.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e\u003cstrong\u003eOrder matters if you use a topical.\u003c\/strong\u003e Wash your hair first, dry the scalp\ncompletely, then apply the treatment. Washing within four hours of applying minoxidil throws that\ndose away, which is the most expensive mistake in this whole routine. If a 250 mL bottle is gone in a\nfortnight, you are using far more per wash than the scalp can make use of.\u003c\/p\u003e\n\n\u003ch3\u003eWhat to expect\u003c\/h3\u003e\n\u003cp\u003eThe effect is cosmetic and it arrives on the first wash. Hair that is clean and free of build-up\nsits with more volume and looks denser at the root, and that is what this product does on day one and\non day ninety alike. There is no month at which something else appears. It will not regrow hair, and\nthere is no reliable evidence that it slows shedding.\u003c\/p\u003e\n\u003cp\u003eIf you are counting hairs in the sink, look at what you leave on the scalp rather than at what you\nrinse off it. A shampoo is the easiest part of a routine to change and the least likely to change\nanything.\u003c\/p\u003e\n\n\u003ch3\u003eWarnings\u003c\/h3\u003e\n\u003cp\u003eFor external use only. Keep it out of your eyes, and rinse with plenty of water if it gets in. If\nyou react easily to fragrances or surfactants, patch test a little on the inner forearm and leave it\na day before washing your hair with it. Stop using it if your scalp becomes red, itchy or sore, and\ndo not start it on a scalp that is already broken or inflamed.\u003c\/p\u003e\n\u003cp\u003eThis is a cosmetic product rather than a medicine. It is not intended to treat, cure or prevent\nhair loss, and hair loss that is sudden, patchy or rapid needs a doctor, not a new shampoo. The\nbiotin here is topical and rinsed away, so the blood-test interference that matters with\noral biotin does not apply to this product. If you also take the\n\u003ca href=\"\/products\/biotin-gummies\"\u003eBiotin Gummies\u003c\/a\u003e, that warning does apply, so tell whoever takes\nyour blood.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eKeep out of reach of children.
