using for a few weeks now! about 6 uses in and noticing a slight difference! biggest thing to keep in mind is to GO BY DIRECTIONS! it’s useless if you don’t! only shampoo no conditioner before using, make sure hair is 60% dry, rub in ur hands before applying, wait 4 min before applying anything else

Not only was the shipping much longer than stated, its a fake product. I still had a tiny bit left of the one I got right from Sephora to compare, and this one is watery and smells like straight alcohol. The one from Sephora is creamy and smells nice. So now I have to go out of my way to return it for a refund. I guess that’s what I get for ordering a different company than Sephora or right from k18 themselves.

I have used this in the past and happy with how it made my hair feel. For some reason this order does not give the same results. Not sure if there was a change in the formulary. I am hoping this was authentic.

I just used this as soon as I received it and my hair feels fantastic. The directions state to use the next 4 washes and I will be doing that. My hair had been pretty damaged and felt terrible and brittle and I feel like it has some life and shine now.

I’ve been a hairdresser for over 15 years and this is the one product I consistently recommend for repairing, strengthening, and restoring damaged hair. K18 is on flash sale on TikTok Shop right now — cheaper than retail, free shipping, and there’s a $5 coupon. 🤯Both sizes are in stock but I don’t know how long this deal will last. @K18 Hair  #k18 #k18results #tiktokshopfinds #damagedhair #hairrepair
