It’s soo expensive, BUT ITs soooooooo GOOD. Look I had virgin hair (black) and I went to get a balage honey blond hair color. Well the colorist forgot balage and gave me root to tip highlight?? God I looked horrendous, I cried so much, no wonder I looked like an alien with all the foil. The colorist literally canceled his plans and redid the color the same day. So basically I left with somewhat blond hair but it was like straw. So for the past 1.5 years I’ve been buying THIS TO RESTORE MY HAIR. It’s almost getting back 

Definitely noticed a difference, but not my favorite.  Works best with 0 first  

I use multiple Olaplex products and the No. 3 is the best of a great line of products.  It really does repair heat and bleach damaged hair.  I use it weekly and leave it on overnight when I can.  The longer it’s on my hair, the better it seems to work.  I’m going to increase to biweekly as my hair is fine and fragile, and this  product builds strength and resistance to breakage.  The large size is a wonderful value when it’s available!

While I use the whole line, I really think number three has transformed my hair! Kudos for making such a great product!

If you haven’t used this product yet LEMME TELL YOU to stop what you’re doing and try this asap!! Has changed the integrity of my hair and I’ll never look back! Decreased frizz, increased smoothness, stronger strands and less split ends, what else should you ask for!!

Overall I'm very lazy with my hair. I've found this is a quick and easy way to strengthen my hair. I've notices my coils are more....coily lol. Also wash and goes are possible because my coils stay defined even after drying. Stable product for sure

I want this to be more effective than it is but I do notice some improvement when I use it so I keep purchasing despite the moderate value for the price - I do notice less fallout in the shower and I can go an extra day without my hair getting so greasy another wash or douse of dry shampoo is required. 

This and the bonding oil are my top 2 hair products. I have a lot of natural coarse wavy frizzy hair and I leave this on my hair overnight or for at least 4 hours.

First time the user of Olapex. I have short, grey curly hair that tends to get very frizzy, dry and brittle. I decided to give it a try after reading about it and so far the results have been good. I use it  twice a week and my hair feels silky and moisturized, and my curls are easily defined and shiny. 

I had high hopes for this shampoo combo. After the first couple tries my hair started falling out in chunks.  I did not think at first that it was a shampoo issue but doctor confirmed today that it is. I am now treating my balding. It’s ridiculous. Do not buy. It’s not worth the risk.
