Male Pattern Baldness (androgenetic alopecia) This is when the hair starts to thin at the temples and crown. It usually starts in early 20’s and is often hereditary, yet this is not always the case and self misdiagnosis is common. It is caused by an increase in male hormones namely androgen & testosterone. Excess testosterone starts in males at puberty. In women pre-menopause, poly-cystic ovaries or diabetes can all cause an increase in testosterone. Stress and diet are also factors. If diagnosed with MPB or FPB laser treatment (see Laser Hair Restoration page) will stop and reverse the hair loss along with the laser products. The earlier treatment is started the better a response will be seen. Regular treatment No 1 with lots of stimulation will help slow MPB and will produce new hair growth.
