Allergic reaction on scalp and face

The serum reduced by hairfall by a great deal. But I can’t continue using it because of the side effects. My scalp is extremely itchy and irritated every time I use it. My face has had a very horrible reaction too. Af first I thought it was due to a change in skincare routine. I switched back to my old routine but the skin reaction continued. I have never had an allergic reaction to any skin carr or haircare product in my life. This product is extremely strong and has a very strong fragrance.

10/10

I put my fine, low-porosity 3A hair through a lot of heat damage. I’m talking blowout brushes, thermal brushes, and of course, a straightener. Oh, and throw in an unstable thyroid, anemia, and other vitamin deficiencies in there as well (working on it!). When I got COVID for the first time earlier this year I noticed quite a lot of hair shed. I’ve cried in the shower—it was THAT bad. So this, coupled with my love for heat tools, meant that I needed to protect my hair and nourish it as much as possible. I was also skeptical about this serum, but ohhhh my! Worth every cent. While I haven’t noticed a quick rate of hair growth (again, most of it being due to the heat tools as well as my own health problems), I’ve noticed that my hair is stronger and the fallout is basically nonexistent. Baby hairs are growing in. Balding patches are getting filled in. As much as it pains my wallet, this will be a happy repurchase for me time and time again. I love many Kerastase products, especially the curly ones, but this is my holy grail. The trick is to use consistently!! As in, every day if possible. Massage it in for a few minutes and because the formula is so watery (which I prefer), it almost feels as though you don’t have anything sitting on your roots. I was afraid my hair would get greasy quicker but that wasn’t the case at all. I highly recommend this to anyone whose hair and scalp need extra nourishment.

Smells like straight rubbing alcohol!!!

I have used this serum and honestly loved it. I bought another bottle as I was almost out of the serum. I decided to keep my old bottle and use it for oil I make for my scalp. I opened the new bottle and the strongest smell of straight rubbing alcohol hit me like a mac truck! It actually scared me. I grabbed my old bottle that I luckily kept and compared. The old bottle didn't smell of alcohol AT ALL! I have had this new bottle for a week and have been trying to read reviews and find out if something changed. I have found nothing. I cannot believe that putting this product on my hair will not damage and dry it out. I literally just cannot bring myself to use it after I have worked so hard on getting my hair healthy. Something doesnt seem right about this. Has anyone else experienced this?!?! I have recommended this product to friends in the past, but now I cannot consciously recommend this serum as I don't feel putting straight alcohol on hair and scalp is healthy.

This serum works great in tandem with the serum in the gold bottle, I can’t remember how to spell it. But I was malnourished after having brain surgery and experienced hair fall. It happened so fast and now I’m on the Genesis system and this serum is really helpful! I’ve been using it for about a year and a half and my hair is stronger, it’s not falling out in the shower and I have significant regrowth. I love it and will continue to use it to keep my hair strong and growing!

I have been using the Genesis shampoo and conditioner for about a year and have noticed a real difference in the condition of my hair. I have shine and have alot less breakage and hair loss.

Kerastase Genesis

I bought this product hoping it would help with my thinning hair, and I’ve been genuinely impressed with the results. After just three weeks of consistent use, I started noticing a real difference—my hair looks fuller, feels healthier, and even seems to be growing in areas that were noticeably thinning before. It’s given me a big boost of confidence, and I couldn’t be happier with the progress so far. If you’re struggling with thinning hair like I was, I can’t recommend this product enough—it truly works!

Doing Okay So Far

I havent been using it long but my review is based on the fact that I can use it on dry hair and it does make your scalp/hair greasy or anything. My only thing is the smell is subtle but strong. I try not to use it on dry hair right before bed otherwise the smell can be a little strong when trying to sleep. I would recommend just making sure the product dries fully if it bothers you, after that the smell is no issue.
