Your hair grows in cycles. These cycles consist of a growth cycle, followed by a resting cycle and then a fall out cycle. To maintain hair that is full and thick, your hair growth rate must exceed or at least be equal to your fall out rate. As the growth cycle slow, the hairline recedes and begins to thin in areas. It eventually falls out. A hair restoration formula can help you keep your hair and even restart the growth cycle so that your hair is thick and full once again.
There are basically three different types of hair restoration formulas, herbal, organic and pharmaceutical. Each of these claims to have very high success rates. In the end, you have to choose the hair restoration formula that works best for you. You may find it necessary to try more than one treatment for your hair loss.
Herbal
Herbal hair restoration formulas use herbs and Chinese medicine to treat hair loss. They typically work internally to keep your hair in a growth cycle. Some formulations eliminate DHT (DeHydro - Testosterone). DHT is considered the "bad testosterone" and is has to its credit as being considered the leading cause of male pattern baldness. When these herbs eliminate the DHT, they allow new hair to grow which, in turn, makes your own hair thicker. Many of these types of treatments also claim to work on all areas that are experiencing baldness such as a receding hairline, thinning hair, baldness and splotchy bald patches.
Organic
Organic hair restoration formulas are free of pesticides, hormones and chemicals. They are all natural and work to naturally restore your hair's thickness. These products claim to be good for the environment because they are all natural and they also claim to be gentler on the body than other shampoos and conditioners that are heavily processed. These organic formulas have ingredients such as jojoba oil, wheat protein and organic fennel oil. The logic behind using all natural ingredients is that restoring the natural elements to your hair's diet you will, in turn, restore your hair's original volume and texture. All this is said to be done with out any side effects that are found in chemical additives that can be toxic to the body.
Pharmaceutical
There are currently two products on the market that are approved by the FDA to treat hair loss. Propecia is taken orally and Rogaine is applied topically to the scalp. Propecia eliminates hair loss by reducing the body's amount of DHT. It actually inhibits DHT formation in the scalp which, in turn, helps to regrow visible hair and can reduce the incidence of hair loss progression.
Rogaine is a hair restoration formula that employs minoxidil and is applied directly to the scalp. This product works by revitalizing hair follicles that have shrunken and basically shut down hair growth. When the hair follicles are revitalized and their size is increased, hair regrowth may occur.
