Highly Recommended by Famous Hair Colorist to the Stars

I purchased this because it was highly recommended by Famous Hair Colorist to the Stars, Jack Martin. So far I love it.

A bit better than Olaplex

This has been on repeat everywhere as the great thing since sliced bread, except for hair (hey, Betty White was born before bread was sliced...sooooo). Anyway, I find that this is a nice leave-in but haven't seen any significant results. I've used it 6x consecutively over the past few weeks (I only wash my hair a couple times a week). Olaplex did basically the same thing except you had to wash that out. This is more convenient as a leave-in. Still trying to figure out what the big deal is especially at the price point!

Disappointed

My hair looked and felt better the first (of initial six) time I used it, BUT after that and the other applications, my hair went back to feeling dry and dull.

Game Changer!

Excellent product. I have a closet full of hair products and by far this is the best.. I have been dying my hair for the past 50 years and it has taken a toll on my hair. This product has brought back life to my hair... unbelievable... A bit pricey but worth every penny!!

Eh...

Maybe my hair isn't as damaged as the other reviewers but this didn't seem to do much. It didn't hurt it but it also didn't change the condition of my, on the dry side, hair.

Soooo soft

I had high hopes for this product because of other things I have seen online, and it rose to the occasion! It made my hair soft, smooth, and easy to style.

Expensive but good

Pros: Saves time that you don't use conditioner. Makes hair soft and manageable without having to apply other products. Cons: Expensive for a small bottle and I need to use more than the directed amount even though I have midlength, fine hair. I've only used it for a few weeks so I can't see if it is repairing damage yet but I liked it enough to buy again.

This is a great product. Helped my hair be less frizzy and left it feeling super soft. Follow the directions carefully. Overall I would buy this again.

Obsessed

After a few uses, the results are obvious. My hair feels stronger and looks healthier. It's really easy to use and incorporate into my regular routine, which is a bonus, too! I will definitely be repurchasing.

Holy Grail of hair products

My hairdresser gave me a sample of this. I loved it so much, I immediately came online to purchase it. LovelySkin had the best pricing, as usual. I can't live without this. I used it the first 5 times I washed my hair and then once a week after. My hair has less frizz and looks great. I do have blonde highlighted hair. I can't recommend this enough!

The end of "Frizzy hair"

I have grey, silver medium length hair that tends to be frizzy due to processing and curly hair in a high humidity area. It took 5 (3 pumps) treatments before I started seeing a noticeable difference. My hair is softer with more defined curls. I wash my hair at least 2 times per week. On the off days, I have started using one pump on my dry hair just to keep my hair soft. I have not needed a leave in conditioner. The only reason it's not 5 star is due to high cost.

Caution

I have healthy long blonde hair that’s textured hair. I sparingly add heat and maintain my blonde in a salon using products from a different brand. I decided to give this a go and help with frizziness. I followed the directions exactly on the box. I used clarifying shampoo. Towel dried my hair and applied small amount from root to end, focusing more on the ends. I used a blow dryer on cool setting smoothing out with a brush. I instantly noticed my ends were just snapping off. Not typical for me! My hair felt sticky like I applied glue to it. When I finished blow drying, my hair was so dry and looked million times worse. It was awful. It ruined my hair!!! I spent extra money in the salon doing conditioning treatment along with a different treatment. My stylist was like, “What did you do to you hair?” On top of that she had a hard time getting the color to stick to my hair. I was in her chair for 4 hours. This stuff is garbage. I returned it. There was no way I would use another treatment. Stay away!

Just buy it!

This hair mask is amazing. I love how easy it is to use - you just skip conditioner and use it after you get out of the shower. No rinsing necessary. My hair looks super healthy after I use it.

The jury is still out for me on this product

I can't give this product a high rating yet. I have used it about 6 times and have gotten uneven results. I know it is highly touted by Instagram hairdressers as a miracle product, but I definitely haven't experienced that miracle. Possibly with continued use......I don't always blow dry my hair and since it is heat activated I haven't had continuous use of the product. I definitely get better, smoother results from other products I have reviewed on this website.
