I was going to wait a bit longer to review this product as I've only had it for about a month, but i really am loving it already. i definitely can see the difference in my ends. i use all the serums (potentialiste, genesis, extensioniste + now serum therapiste) as i know they each do something different and my hair needs all the things!! All the help!! Now, when i apply all the serums, i definitely feel like I'm helping to make my hair healthy and it FEELS/LOOKS like it's healthier. The ends of my lengths look shinier (but not greasy )So if you're on the fence, buy it!

So this product was actually recommended to me by my friend who use to work at a salon. I saw her apply it one time after going to the beach because her hair got all frizzy. The way it immediately made her hair look so soft and silky I was in utter shock. I asked her to apply it to my hair so I can test it out . It literally made my hair feel so smooth and no more frizz! Also the scent of it is immaculate. I can’t recommend this product enough. FYI this product does NOT leave your hair excessively oily at all!

Amazing!

While salons were shut down during covid, I made the very unwise decision to put Sun In on my hair and go over it with a hot flat iron while it was still damp. Don’t judge, no one was in a good state of mind during that time lol. I’m sure you can guess what happened. Several large chunks of my very fine, already damaged from highlights hair literally melted and broke off about 1/2 inch from my scalp. Enter the very high bun that I had to wear every day for months to hide the large sections of hairs sticking straight up on the top of my head. The last two years have been all about finding products to maintain my hair’s integrity as it grows out, and this has been an absolute life changer. My hair feels silky, thicker, and healthy when using this. It’s not weighed ... MoreWhile salons were shut down during covid, I made the very unwise decision to put Sun In on my hair and go over it with a hot flat iron while it was still damp.

Can't do without this!

Was dubious of purchasing as every other serum I've tried on my fine hair hasn't been any good and wasted money. Well I hit the jackpot with this one! It smooths out my frizzy, unruly fine flyaway overdyed locks. I use on towel dried hair before drying and styling. Just need to use a tiny amount, rub between palms and spread from mid length to ends. Stops frizz and hair looks much healthier. Glad I purchased and it lasts for quite a while which is a bonus.

I Have Learned How To Use V2 Of This Product

I used the old version of this and could not figure out how to use this new version without getting oily hair. You need a full pump to get both sides to spit out product. I dry my hair in thin layers and like to only apply a tiny bit of product to each layer. I figured out that if I dispense a pump of this into a spoon I can mix it and just get a little on each layer, distributing it evenly throughout my ends. This works better to me with heat. Like it drives it into the hair. It makes my 54 year old bleached hair soft and shiny. Makes it a little harder to get curls to hold, but that is a small price to pay. It is expensive, but it does a great job.

Love Kerastase Therapiste

I love Kerastase Serum Therapiste and find that it's the only product that works for me. I've tried other products over the year and always regret it. This is the hands-down winner for me! I also found that ordering the product through LaLa Daisy was great! They shipped promptly and the product was well-packaged. Thank you LaLa Daisy for carrying great products, offering great pricing, and providing great service!!

Not the right product for me

Don't really like this particular masque and serum at all. I have used and loved Kerastase products for several years. However, this one makes my head itch,and I don't particularly like the smell; it also seems to make my hair greasy and dull; I just don't think it is right for me. Would like to return these and/or be refunded. Will stick with the ones I have already used and like better!!

Not worth the money and the pump needs some work.

The pump on the top worked ok but only one liquid was produced no matter how many times I pressed it.I removed the very top piece with a flat driver and manually pressed tube attached to the other side to squeeze it out, then I put the pump back on.After that, it worked fine.However, even though the clear oil and white serum are mixed and put on the towel-dried hair, I felt the end of the hair was just ok, not amazingly hydrated unlike other reviews, including on Amazon site.I don’t think it’s worth the money for the job it does.

Waste of money, my hair is worse than before

Honestly I was expecting a lot and received nothing but direness out of these mask, this product claims to repair your hair, but my split ends are more visible since the 1st time I used this product together with the serum. I don’t mind paying an expensive cost for something that will do the job, but I feel ripped off by Kerastase! My hair is worst than before and my wallet is -$100… what a waste!!I want to return this products and get my money back, seriously alfaparf is way better!
