Review (4/5): Lightweight Shower & Conditioning Caps
These are perfect to use a few times when you do a hot conditioner on your hair. They are not the heavy kind that last, but perfect in certain situations. They are similar to hotel shower caps. Easy to pack if you are going to be someone's houseguest.
Great for deep conditioning your hair. Slather on the conditioner, put on the cap, and wrap a hot towel around your head.
