While I have been off work I have been playing around with cowashing and mud washing. I keep my mudwash simple with calcium bentonite, sodium bentonite, acv and water. In the past I had tried leaving the mud on longer to see if I had better definition. However, this past week I found that it worked better if I applied the mud, let it sit for a while, rinsed and then applied it again. My hair was smoother and I had more definition. After I rinsed out the second mud application my hair felt conditioned and as if I had put oil in my hair.
In the future when I have time I will apply mud twice. At some point I may also try the mud without the ACV. However, it makes it so easy to smooth out. Without it my mud comes out lumpy.
