Intolerable smell

This product smells awful. Like the yeast byproducts of making beer or worse. I literally couldn’t sleep after trying it for an overnight treatment, it was that strong and that bad. I was really stunned because everything else I’ve tried from Olaplex has a pretty mild pleasant/neutral scent (No. 3, 4, 5, 5 leave-in, 6, 7, 8, 9). Returning this; even if it somehow provides good benefit to the scalp there is no way I could tolerate that smell ever again. The bottle even suggests you could use it as part of your styling routine— go out in public after applying that?! Absolutely not. Anyway, I do not normally write reviews but I wanted to provide this PSA to y’all— do not waste your money on this one. Will stick with my other Olaplex faves; I do highly recommend No. 4, 5, 5 leave-in, 7, and 9.

Pleased

I bought this product when it first came out. I use it once a week, the night before I wash my hair. I have noticed there is less hair in my drain after washing my hair. Also noticed more little hair growths. Only downsize is the product smell. It is not a pleasant smell.

Love using scalp longevity cream.

This product feels absolutely revitalizing to the scalp. I get my hair colored and the scalp will feel dry and itchy. When I put this on the scalp and massage it in it actually feels as it the product just gave me a super healthy scalp. I like using it at night after massage so it can help all night.

So far it great

First use and I have high expectations. I color my hair every 4-6 weeks it's gray. My scalp has gotten tight, dry and itchy no flakes. Also thinning. I decided to use it as an overnight treatment on dry sort of dirty hair. Tomorrow is was day. My scalp feels soothed, less tight,moist but not greasy - and the dry itchiness is gone. I can't wait to wash and try on wet hair, and see how the next few weeks progress.
