Before I tried this product, I viewed Olaplex as a brand for people who were born with good hair and just went to the salon to drop a few c-notes to get a touch up. I'm not one of those people. With hair, I am very low maintenance, preferring to wet it and forget it (antithetical to Olaplex in my ...

Not for me
I really wanted this scalp treatment to be a win, especially since I usually love Olaplex' products. Their shampoo and conditioner have been staples in my routine for a while, so I had high expectations going into this. Unfortunately, it didn't quite deliver on what I needed it for. To start with th...

Really works!
I've been using this for a few weeks and I'm happy with it. I struggle a lot with a dry scalp. I don't have dry hair though. So it's hard finding good hair products for me. Dandruff shampoo helps my scalp feel and look better but my hair doesn't respond well to it. I like my salon shampoo. So I knew a scalp treatment would be great. I follow the instructions and it's made my scalp so much more moisturized! I love the applicator tip because it makes it easy to apply to my scalp through my thick hair. My scalp is clean feeling and not itchy. I'm very happy with it! Highly recommend! This product was provided for promotional purposes in exchange for my honest review.
Great for people who exfoliate their scalp
I used this for 3 weeks. It's like using lotion for your scalp, which I think can be essential if you have a dry scalp (especially if you do hot showers). This product was provided for promotional purposes in exchange for my honest review
I would buy this product again
I love lapped so much and I so like this product however there are many other products in the line I prefer and I'd still buy it my hair felt healthier

Holy Clean!
I *loved* this product, way more than I expected to. I'll admit, I was skeptical at first and wasn't sure it would do much for me, but I was so wrong. The serum-like texture is lightweight and easy to work with. I applied it in three sections on my scalp and gently massaged it in, using it on freshly washed, damp hair. I have a naturally oily scalp and dark brown hair, so oil buildup becomes super noticeable for me very quickly. Usually, I have to wash my hair every other day or risk looking greasy. This treatment changed that completely. It extended my washes to three, sometimes even four days, which is a huge deal for my hair type. I was genuinely shocked at how fresh my scalp stayed. A little product goes a long way, which makes the bottle feel even more worth it. It never felt heavy, irritating, or greasy on my scalp. Just clean, balanced, and refreshed. I can confidently say this has been a game-changer for managing oil and extending my wash days. I'm officially obsessed.
