If your scalp is not washed regularly and kept clean, there can be a build up of chemicals on the surface. When your hair naturally falls out, this build up of chemicals can prevent new hair growth from penetrating through the surface. If your hair does manage to penetrate, the new growth tends to be somewhat weaker and more prone to falling out. Hence hair loss results.

Washing your hair using a mild shampoo on a regular basis and ensuring that you thoroughly rinse away any residue is enough for most of us to stop the protein build up on your scalp. The act of massaging the scalp during shampooing also acts as a stimulant for the blood circulation to the hair follicles, so helping to promote new hair growth.

So to pre-empt your next question, if regular shampoos do all of this, why use a special hair loss shampoo? If your hair loss is caused by your hormones, the drugs contained in these products work with your body to bring your hormones back into balance. As a result of suppressing certain hormones that prevent hair growth, your hair should be able to grow back again. Hair loss shampoo will also keep your scalp clean and healthy by having the same benefits as using a regular shampoo.

Naturally, any product that affects your hormone balances can cause side effects, and you should be fully aware of these before starting treatment. But if you are interested, the hair loss shampoo products that tend to work the best are the ones containing either the chemical Rogaine or Propecia. (Both of these drugs were approved for use by the FDA back in 2001.)

However, before buying one of the hair loss shampoo products, I would advise to consult a medical professional to ensure that the cause of your hair loss is hormonal. If it isn’t then it is unlikely that these products will work for you.
