From CRISPY to SILKY

I have gray, 4C-gray natural hair. Finding a system that nourishes her is hard to find. (She's so special!) I washed my hair with the KANUNI BROWN HydraCurl Shampoo and conditioned with the Avocado & Quinoa Protein Repair. First, I put way too much shampoo in my hand to start. This system is potent. A little goes a long way and it truly delivers. For a first-time wash and condition with this system, my hair felt "cared for". I apply the Biotin Repair Serum to the strands and tips every 2-3 days and twist. It makes my hair soft and frizz-free. It seemed to knit my fuzzy ends together while silkening the strands and putting a beautiful shine to the silver. This system ACTUALLY DOES what it says it will do. It is a keeper!

Soothing and calming to my scalp

After years of a daily itchy scalp, Kanuni Brown has come to my rescue. With intense itchiness I would massage my scalp with my fingers, pat my head rapidly, use a battery operated scalp massager and even scratch my scalp with my nails. All with only momentary relief, and then I discovered Kalani Brown. With my very first use, I appplied a small amount to the itchy scalp area, and gently massaged it in. Within seconds the itchiness subsided and did not return for a several days. So now as part of my new hair care journey, Kanuni Brown is at the top of my list.

My Hair Thanks You!

I've only used this product for a few weeks. It gives my end a smooth polished look, moisturized with no frizz. I will continue to use this product as a part of my hair care regimen.

Making the whole Kanuni Brown experience even better!

I’ve had a chance to use the Biotin Repair Serum twice now and it’s so good. My hair is even more nourished and the results from my wash last even longer. Definitely making this one a regular part of my hair care routine.
