I have used Trader Joe's Castille soap twice to wash my hair, and love it. I use it as a shampoo and it does not dry my hair, but leaves it super soft. This last time, I washed and then cowashed with VO5. My hair came out soft and luxurious.
I followed up with my moisture mix, some Silk Infusions (CHI), Mango Butter and sealed. Feels good. This product is definitely a keeper.
