Yes, what Dotty said^ I use Musely and use both tret and hq together at night, vit c in the morning. One thing I wish I had known, so I’ll tell you, keep it away from eyelashes and eyebrows. It spreads so keep it like an inch or two away. I was noticing some pure white eyelashes and brows and asked an esthetician, she said it absolutely does bleach to the root.
