My new favorite shampoo for light, clean volume!
Hair Type Wavy Hair
I've been using this shampoo for a few weeks, and it honestly transformed how my hair looks and feels. My roots get oily fast while my ends stay dry, but this formula keeps everything perfectly balanced. It gives a deep clean without stripping, and my scalp feels fresh for days. The texture is creamy but super lightweight, foams up beautifully, and rinses out with no residue. Right after drying, my hair feels silky, smooth, and noticeably shinier — that healthy, natural glow that's hard to get with fine hair. I also love how bouncy and soft it feels, without any heaviness. It keeps my hair clean longer, full of movement, and smelling so fresh. If you want shine, lightness, and that salon-clean feeling every wash — this shampoo is worth it.

Great shampoo
Hair Type Very Curly Hair
I really like this No. 4 Fine Bond Maintenance Volumizing and Strengthening Shampoo. It smells amazing and cleans my hair really well. I have fine hair, so it's perfect for me because it doesn't leave my hair feeling oily right after washing. With other shampoos, my hair would start getting oily in just a day or two, but this one keeps it feeling fresh and light.
Seriously, buy it!
Hair Type Wavy Hair
I've used this shampoo for the past week and the results were pretty good! Absolutely loved it. It seriously does help your hair if you suffer from like breakage and dullness. I loved that it left my hair so soft like a pillow. I would 100% recommend it! received as a part of an educational promotion

Lovely smell, easy on hair
Hair Type Wavy Hair
*I was given this product in exchange for my honest review* This product is not too stripping of oil in the hair and is well-balanced. I pair this with the no.4 fine bond conditioner and it works quite well but the shampoo is very compatible with other conditioners.
