When my hair is curly, I use Suave coconut conditioner. It's not a leave-in, but I use it like one. It is so light and really brings out my hair's curl. A lot of leave-ins are too heavy, but this one is just perfect. When it's straight, I love Frederick Fekkai Tech Shampoo & Conditioner and their Olive Oil glossing cream.

I use Pureology Shampoo and Conditioner, and after shampooing, I'll put the conditioner on, go watch a movie, and wash it out later. When you have black girl hair, once we wash, we've gotta do the whole press and get in the edges and everything. That's a lot of heat to go back to straight on a daily basis.

I used to love those little cute bottles of amenities in the hotel room. And while the soap, shampoo, conditioner, and lotion may smell great, they waste an incredible amount of plastic and space in your luggage.

On tour, there's dry shampoo - I use the one by Bed Head.

If you can't find dry shampoo, baby powder is great.

Moroccan Oil shampoo is my miracle product. My hair becomes so manageable and silky after using it.

'90s fashion is awesome. Best of both worlds - you had power pop, like the Spice Girls and Shampoo. But then you had Nirvana and Hole. And you also had '90s dance music like N-Trance, who kind of blended both.

I have always used Pantene hair products since I was a child, since I was 9 or 10 years old when I began to shampoo and condition my hair. I have also always been 'obsessed' with the brand's beautiful ad campaigns.
