Bringing everything back to the INCI list, THE INKEY LIST’s line-up of purse-friendly products prove that efficacy needn’t cost the earth. Developed by a team of leading scientists, this range aims to cut through the industry jargon with straight-talking products that harness the best and the breakthrough ingredients staking their claim to the shelves of the experts who know a great thing when they use it. And now that the team have applied their unique expertise to the realm of hair health, prepare for your lengths to have never looked better…
If you find that you’re moulting more than usual, or feel like your hair is increasingly thin, THE INKEY LIST’s Caffeine Stimulating Scalp Treatment was made with you in mind.
Clinically proven to reduce and prevent hair loss (after three months of testing, 85% of testers showed significant improvement), this overnight treatment invigorates stem cells to optimise growth and increase your hair’s thickness. With 1% caffeine powder – a stimulant that kick-starts sluggish follicles – alongside 1% Redensyl (which both supplements growth and helps counteract fallout) and 1% Betaine to soften and nourish each strand, this helps to build body for lustrous locks.
We recommend shaking the bottle before use. Use as an overnight treatment. Shake into the palm of your hand, massage hands together, use your fingertips to rub into scalp and leave on overnight. Apply enough to cover entire scalp. Wash hair as normal in the morning, if desired. Use every night for best results over a 3 month period.
1% Caffeine Powder – helps to stimulate scalp and hair follicles
1% Redensyl™ – helps to improve hair growth while reducing hair loss
1% Betaine – helps to condition hair, leaving it soft and silky

Not sure if it works.
I’m not sure whether or not it actually stimulates the hair growth, but it doesn’t make your hair greasy for the next day, so that’s very nice and unusual for this type of product!
Report this reviewBest of the best
Best serum i have ever tried, not only for hair growth but it keeps my oily hair fresh for days bought already 6 bottles and will keep on buyingÂ
Report this reviewEasy hair care
I love this product as a leave in treatment for the night. I feel that it strengthens the hair and stimulates the scalp for hair growth. Good product, keep purchasing it! B+++
Report this reviewOkay scalp treatment
I used this every night for six months. It felt cooling on my scalp and did not make my hair greasy. But I didn't see any difference in hair growth/preventing hair loss.
Report this reviewNice product
First time using, but so far looks nice. Easy to use. Let’s see :)
Report this reviewGreat product
The caffeine really helps with my hair growth and it doesn't weight down my hair. I'm on my second bottle and will definitely repurchase it.
Report this reviewGreat
I am on my third bottle. This product really helps with hair loss and hair growth.
Report this reviewGreat
I repurchased it several times. I use it twice per week and i can see it helps to maintain a healthy scalp and boosts hair growth. Highly recommend this product.
Report this reviewSo far so good
I've been using this product for a month and I can say some little baby hairs are growing. It's not a miracle but I think it can help in this moments of the year with a massive hair loss.
Report this reviewIt works !
Give it a go if you need a hair growth boost. I’ve tried some significantly more expensive treatments and saw same or less improvement. I got a small bottle as part of one of CB goodie bags and at first wasn’t consistent enough to see the difference but after recently having had a baby I found myself shedding WAY MORE then I grew during pregnancy. I became desperate and willing to try anything really. Then I remembered that I have this serum and started to use some at night 4-6 days a week. After 3 weeks of consistent use I noticed a bunch of new hairs coming up above my forehead and in my part, like noticeably more! I then realized that I’ve only been selectively applying the serum in those areas. I ordered more and now apply it all over my scalp. This does work but like w any product you have to use it as directed ( and it’s directed to be used multiple times a week ).Â
