Find the cause of excessive Hair Growth
Before you decide on getting rid of back hairs it is advised that you must try and find the reason for it. This is because sometimes the excessive hair growth is due to some unevenness in the hormones. Hence you must first of all consult a doctor to find the reason for the hair growth otherwise the steps you will take for removal will be of no use.
This technique is used to permanently remove the back hairs. It involves giving shock to the hair follicle to such an extent that it does not grow hairs anymore. This method is quite costly and also quite time consuming. It continues till the back hairs become thin and eventually stop growing.
Although electrolysis is quite effective in order to get rid of back hairs permanently, but many cannot afford it. On the other hand, laser therapy is comparatively cheaper and involves minimum risk of damaging the skin. Somehow, it is advised to get it done from a renowned therapy center in order to avoid any complications. The process simply involves sending a beam of laser light down in to the hair follicles to destroy the roots. This only disables the hair roots without doing any damage to the skin around the area.
If the above two methods are not quite affordable for you then there are some home remedies you can try. Generally, these remedies are known as sugaring and waxing. It involves heating the wax which is then applied on the back. A strip of cloth is flattened over it which is then pulled off in the opposite direction of hair fall. Waxing doesn't permanently remove hair, but it reduces the rate of growth and also makes the hair thinner. Generally you'll require waxing once a month.
