Although horse shampoo may cleanse and condition the hair, it will not make hair grow. People who use this product may believe that it helps with hair growth because the product actually causes the hair shaft to swell, so hair looks fuller.
Horse shampoo may harm very fine hair. For hair to grow and be healthy, it is important to condition and strengthen it through the use of moisturizing conditioners and shampoos that contain protein. A scalp massage may also be beneficial for the stimulation of blood flow to this area. Eating a balanced diet that is rich in protein and vitamins may also help with hair growth. Another thing that may help is taking daily vitamins that contain Vitamin B derivatives, antioxidants and minerals like zinc and iron.
