In 2007, a German study showed some evidence that caffeine was able to stimulate hair follicles and activate hair growth under laboratory conditions. This prompted the production of various caffeine-based shampoos, including Alepecin, which claim to aid hair growth, but do caffeine shampoos actually help to grow hair?
Dry shampoo is not good for your hair. It can cause dry, brittle strands and among a host of other negative side effects, it can clog your pores and suffocate your follicles. If you are a women with thinning hair, then it is a very common misconception that washing your hair every day results in more hair loss. This is not true and using a dry shampoo to avoid daily hair washing is doing so much more damage than washing it more frequently could ever do.
