OlaplexNo.4 FINE Bond Maintenance Shampoo, Ultra-light, Clinically Proven Fine Hair Shampoo to Volumize & Strengthen (8.5 Fl Oz)

My fine hair felt fuller, stronger, and way more manageable after just one wash. It’s lightweight but still incredibly moisturizing, leaving my hair soft and shiny without weighing it down. Plus, it smells amazing – like a spa day in a bottle. This is definitely a staple in my haircare routine now.

I've used the Olaplex shampoo and the whole Olaplex system in the past (for a number of months). While I think the system is mostly hype, I'd forgotten how much I liked the shampoo. It has a consistency almost like honey, but it lathers up easily with a very mild, unisex scent. Makes my fine hair clean and bouncy and soft.

Left my hair drier and more flat than ever. Enough said

I have long, blonde hair that tends to be drier from full highlights every 3 months. It’s probably closer to medium than fine, but I have a lot of it, so most shampoos make it fall flat, but Olaplex N.4 actually gave it a nice lift at the roots which lasted almost 2 days. I’ve used Olaplex (for Blondes) in the past, and was right to expect the same very thick consistency, with a light, pleasant scent. The bottle is small, but only a small drop is needed to get a really nice lather going, and get hair nice and clean. I do find Olaplex N. 4 slightly drying, especially for bleached/colored hair, and you may need to use a rich conditioner, or additional oil/leave-in (I used some hair oil and my hair felt soft with great lift) Price is a little high, but on par with higher end brands.

Awesome shampoo. Leaves my hair soft and shiny. Looks much healthier.
