If I'm wearing my natural hair unstretched or in a bun, I would moisturize with S-Curl, African Royale BRX Spray, and/or Aussie Moist Conditioner. I've tried Hawaiian Silky 14n1 before but it caused build-up on my hair.
If I'm wearing my natural hair stretched out (like in some variation of a twistout), I moisturize with either Ultra Sheen Creme Satin Pres, Cantu Conditioning Leave-in Cream, or Aussie Moist Conditioner. I've also experimented with Organic Coconut Oil but have found that it makes my hair feel hard if I apply too much on my hair.
If I'm wearing my natural hair straightened with heat, I use the Ultra Sheen Creme Satin Pres to keep my hair soft and shiny. In the past, I have used Hot Six Oil but have ran out of that.
