Love it
honestly i was pretty skeptical about trying yet another high end curl shampoo because my hair usually just ends up feeling stripped or like a tangled mess but the olaplex n4 curl bond shaper is actually a game changer for real. i was lucky enough to have this gifted to me to try out and the first t...

Gentle cleansing but not hydrating for drier hair types
I have multi textured strands and multi curl patterned dry type 3 & 4 low porosity hair. True cleansing is imperative for any wash day to turn out good for me. Hydrating shampoos are my favorite to cycle through since clarifying all the time can mess up the moisture balance and ph of my hair at time...

Finally found my holy grail curl shampoo
Hair Type Wavy Hair
I have long, thick, wavy-to-curly hair and I've been on a never-ending quest for a shampoo that actually enhances my curl pattern without stripping it. This one delivers. My curls came out so much more defined and hydrated. They had actual bounce and shape instead of just falling flat or getting frizzy after washing. It lathers enough to feel clean but doesn't leave my hair feeling dry or stripped at all. My curl clumps were noticeably tighter and more uniform from root to tip. I'll definitely be repurchasing and this is staying in my routine!
Soft, Clean Curls Without Dryness
I've been using this shampoo for my curls for a few washes now and I honestly like how gentle it feels on my hair. A little product goes a long way and it cleans without making my curls feel stripped or dry afterward. My hair usually gets frizzy easily, but after using this my curls looked softer and more defined. I also noticed my scalp felt clean without that squeaky dry feeling some shampoos give. The texture is lightweight and it rinses out really well. I paired it with the matching conditioner and my hair felt smoother and easier to detangle. Definitely a good option for curly hair that needs hydration without feeling heavy.
Game changer
Absolutely love this product, it brought my coils back to life in one wash!
Great product!
Hair Type Wavy Hair
This shampoo made such a noticeable difference in my curls after just a few uses. It cleanses really well without stripping my hair, and my curls felt softer, more hydrated, and way less frizzy afterward. I also love that it leaves my hair feeling lightweight while still giving my curls definition and bounce. Definitely one of the best curl shampoos I've tried.
perfect for type 4 hair
Hair Type Very Curly Hair
i have 4b/c hair and it defines my coils. I do recommend pairing it with something more hydrating because my hair feels dry after constant back to back use. but using the set every once in awhile will define afro hair
