Hair cap for hair nutrition

This is a hair cap I bought back when it was being promoted, and I find it great to use occasionally when my hair feels dry and lacks shine. It felt exactly like the cap middle-aged women wear when getting perms at the salon, so I didn't like it much at first. However, once I experienced the shine returning, I understood why they do it. If you apply some hair essence and wear it for about 10 to 15 minutes, your hair becomes shiny enough that you can actually see the nutrients have been absorbed. You don't have to use it every day; using it just once a month is sufficient, so I think it is worth recommending to anyone with dry, frizzy hair.
