Is this product made for me?

If your hair feels rough, tangled or dry after washing, this is the one.

  • All hair types, including fine hair

  • Dry, frizzy or tangled hair

  • Anyone already using Shampoo

Long or curly hair? Keep it in for an extra minute.

How is it different from other conditioners?

Most conditioners make your hair soft, then leave it flat and heavy.

No silicones coating your hair. No sulfates, no parabens, no drying alcohol. Just soft, light hair that still has its volume.

  • Soft in 1 minute. That's all it takes.

  • Zero tangles. Your fingers go straight through.

  • Still has volume. Light enough for fine hair.

  • Built for your shampoo. No.1 cleans, No.2 finishes.

never used conditioner before, big mistake

21 and I'd never used conditioner in my life, I thought it was for people with long hair. One minute in the shower and my hair feels like when I walk out of the barber. Can't believe I skipped this for years

the shampoo + conditioner combo

Using it after the Ultimate Shampoo. The shampoo cleans, this makes it soft, and together my hair feels like a completely different texture. Sounds dramatic but it's true

soft without silicones

I always thought you needed silicones for soft hair, that's literally what a hairdresser told me. This has onion seed oil, argan and sweet almond oil instead and my hair is softer than with any silicone one I've had

growing my hair out without the fried ends

Growing my hair out and the ends were getting dry and rough. This keeps them soft and I can push my hair back without it looking fried. Makes the awkward phase way less awkward

oily scalp and it's fine

My scalp gets oily fast so I always skipped conditioner. Turns out you just keep it off the roots. Lengths only and my hair is soft without my roots getting greasy any faster

didn't kill my volume
