Sep 14, 2013 - With the directions saying to leave in for only 10-15 minutes, I was skeptical that it would work. But this deep conditioner is amazing. It smells soooo good and works wonders. After the 15 minutes were up, I was surprised at how my hair responded. It instantly detangled my 4c curls and left them feeling über soft and well moisturized. I'm definitely in love with this one and will be purchasing a full sized bottle!!!
