Both men and women can experience thinning hair, although the condition is more prevalent in women – especially when they begin the menopause. Too much testosterone in women can also result in the condition.
Treatment can vary depending on the cause of the thinning. It could be dietary – for instance a lack of certain vitamins and minerals – in which case the thinning could be temporary. An over-the-counter treatment known as Minoxidil is believed to widen blood vessels, getting more oxygen and blood to hair follicles to stimulate new and healthy hair to grow. Permanent hair thinning though is usually treated with either hair surgery or Platelet Rich Plasma (PRP).
One form of hair surgery is Follicular Unit Extraction (FUE). A minimally-invasive technique, this involves transplanting individual hair follicles from one area of the head to another (usually the back to the front hairline).
PRP has been used for decades now for treating sports injuries. It’s only recently that it’s found to be successful for hair regrowth. The individual’s blood is removed, put into a centrifuge to condense platelets, then the platelets injected into the scalp. It’s believed these platelets stimulate hair regrowth by repairing damaged hair follicles.
