{"product_id":"rosemary-peptide-serum","title":"Rosemary Peptide Serum","description":"\u003cp class=\"q-lead\"\u003eA daily leave-on scalp serum with rosemary, caffeine, peptides and biotin, in a 60 mL\ndropper. It sits at the cosmetic end of this range, and the honest reason it exists is that most men\nwant a second thing to do for a thinning scalp alongside the one drug that has real regrowth evidence\nbehind it. None of the four ingredients here comes close to minoxidil for proof, and what follows sets\nout how thin each one actually is.\u003c\/p\u003e\n\n\u003ch3\u003eWhat is in it\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eRosemary.\u003c\/strong\u003e The evidence people cite is a single randomised trial from 2015, which\nput rosemary oil against 2% minoxidil in 100 men over six months. Both groups had measurably more hair\nat the end, with no significant difference between them, and the rosemary group reported less scalp\nitching. That is one trial, at one centre, with no placebo group, against a strength of minoxidil half\nthe one we sell. It also used a diluted essential oil applied on its own, which is a different thing\nfrom rosemary in a cosmetic serum, so read it as a reason to be interested rather than as a result you\nshould expect.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCaffeine.\u003c\/strong\u003e Caffeine does reach the follicle and linger there, which penetration\nstudies have measured. In human follicles kept alive in a dish it offsets testosterone's suppression\nof hair shaft growth at very low concentrations, though what a dish shows and what a living scalp\ndoes are different questions. The study usually\nquoted, in which 0.2% caffeine performed no worse than 5% minoxidil over six months, was open-label,\nfunded by the ingredient's manufacturer with company staff among the authors, and counted anagen hairs\nby trichogram rather than measuring density. That is a long way from showing the two are equivalent,\nand nothing published shows that adding caffeine on top of minoxidil improves the outcome.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePeptides.\u003c\/strong\u003e The short signalling peptides used in scalp serums are supported almost\nentirely by studies run by the companies that sell the ingredients, usually on small numbers and\nusually never published in full. They are here because the mechanism is plausible and they are well\ntolerated, and the independent evidence to back them up does not yet exist.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBiotin.\u003c\/strong\u003e Taken by mouth, biotin helps people who are genuinely deficient, and\ndeficiency is uncommon in anyone eating normally. Reviews in 2017 and 2024 both concluded there is no\ngood evidence it grows hair in people who are not deficient, and the one double-blind\nplacebo-controlled trial found no difference. Applied to the scalp it has less evidence again. It is\nin the formula as a conditioning ingredient, and it is fair to judge it on how your hair feels rather\nthan on anything it does to a follicle.\u003c\/p\u003e\n\n\u003ch3\u003eWhy it belongs here\u003c\/h3\u003e\n\u003cp\u003eThis is the serum for someone early in thinning who wants a daily step that is easy to keep up, and\nfor someone who has decided against a drug and would rather do something cosmetic than nothing. If\nregrowth is what you are actually after, the honest recommendation is\n\u003ca href=\"\/products\/minoxidil-topical-solution-5\"\u003eMinoxidil Topical Solution\u003c\/a\u003e, the only thing in this\nrange with strong evidence behind it, and the serum can sit alongside it as the other daily habit. It\noverlaps heavily with the \u003ca href=\"\/products\/caffeine-scalp-serum\"\u003eCaffeine Scalp Serum\u003c\/a\u003e, so choose\none of the two rather than layering both. The\n\u003ca href=\"\/products\/rosemary-onion-shampoo\"\u003eRosemary \u0026amp; Onion Growth Shampoo\u003c\/a\u003e is the matching\nwash, and \u003ca href=\"\/products\/rosemary-hair-oil\"\u003eRosemary Hair Growth Oil\u003c\/a\u003e is the heavier weekly\nversion of the same idea if you would rather use something you rinse out.\u003c\/p\u003e\n\n\u003ch3\u003eHow to use it\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eOnce a day, on a dry scalp, morning or night.\u003c\/strong\u003e\u003c\/p\u003e\n\u003col\u003e\n  \u003cli\u003eStart with a dry or towel-dried scalp. Soaking wet hair spreads the serum through the lengths\n    instead of leaving it on the skin, which is where you want it.\u003c\/li\u003e\n  \u003cli\u003eSqueeze the bulb and fill the pipette to roughly 1 mL, which is about one full dropper for the\n    whole scalp.\u003c\/li\u003e\n  \u003cli\u003ePart your hair into rows across the thinning area and place five or six drops along each parting,\n    rather than emptying the dropper into one spot.\u003c\/li\u003e\n  \u003cli\u003eMassage it in with your fingertips for about thirty seconds. It should wet the skin without\n    running down your neck.\u003c\/li\u003e\n  \u003cli\u003eLeave it in and do not rinse. It absorbs in ten to fifteen minutes, so allow that before a hat, a\n    pillow or any styling product.\u003c\/li\u003e\n  \u003cli\u003eWash your hands afterwards.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e\u003cstrong\u003eIf you also use minoxidil, keep the two apart.\u003c\/strong\u003e Put the serum in whichever slot the\nminoxidil dose does not occupy, or leave at least two hours between them. Layering a second product\nstraight onto a wet minoxidil dose dilutes it and moves it around, and the drug is the part of your\nroutine worth protecting.\u003c\/p\u003e\n\n\u003ch3\u003eWhat to expect\u003c\/h3\u003e\n\u003cp\u003eThe hair already on your head has finished growing, so the quickest changes you will notice are in\ncomfort and feel. An itchy scalp usually settles within a week or two, and\nhair tends to sit slightly fuller from the conditioning ingredients almost straight away. That part is\ncosmetic and it is real.\u003c\/p\u003e\n\u003cp\u003eDensity is a slower and far less certain question. In the rosemary trial nothing measurable had\nhappened at three months and the change appeared at six, so six months is the earliest point at which\nit is worth judging. Photograph the same area in the same light at the start and once a month\nafterwards, because gradual change is close to impossible to see in a mirror. Be prepared for the\nanswer to be that your density looks the same. This is a cosmetic product and it may do nothing at all\nfor the amount of hair you have.\u003c\/p\u003e\n\n\u003ch3\u003eWarnings\u003c\/h3\u003e\n\u003cp\u003eFor external use only, and for the scalp rather than the face. Avoid the eye area and rinse with\ncool water if it gets in. Patch test before the first full application, because rosemary is a botanical\nextract and botanicals are among the more common causes of contact allergy. Put a drop behind your ear\nor on your inner forearm and leave it for twenty-four hours.\u003c\/p\u003e\n\u003cp\u003eDo not apply it to a scalp that is broken, sunburnt, inflamed, infected or painful. Do not use it\nimmediately after microneedling. Published case reports describe granulomatous and hypersensitivity\nreactions when topical products are introduced into fresh microchannels, and peptide serums are named\nspecifically among them, so if you use the \u003ca href=\"\/products\/dermaroller-0-5mm\"\u003eDermaroller\u003c\/a\u003e, leave\nthe scalp alone for twenty-four hours afterwards.\u003c\/p\u003e\n\u003cp\u003eThis is a cosmetic product and it does not treat, cure or prevent hair loss. If your hair loss is\nsudden, patchy or unexplained, see a doctor rather than starting a serum, because those patterns can\nhave causes worth diagnosing. If you are pregnant or breastfeeding, check with a doctor first, since\nrosemary oil is one of the botanicals usually avoided. Stop using it if you develop irritation or a\nrash. Keep out of reach of children.\u003c\/p\u003e","brand":"Quintéa","offers":[{"title":"Default Title","offer_id":57981121528190,"sku":"QN-ROSEMARYPEPTIDESER","price":36.99,"currency_code":"RON","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1019\/9849\/4078\/files\/rosemary-peptide-serum.png?v=1790587773","url":"https:\/\/quintea.eu\/products\/rosemary-peptide-serum","provider":"Quintéa","version":"1.0","type":"link"}
