Short term cosmetic help
Quick and easy and will not make the hair grow back quicker or thicker. However, you may find you have to shave everyday, it may cause irritation and there is unpleasant stubble growth between shaves.
Waxing, threading and sugaring
Can reduce regrowth if done regularly, but can be painful and may cause scarring or folliculitis (inflammation of a hair follicle).
Can make dark hair look better in the short term, but may irritate your skin and is not effective for everyone.
Hair removal creams are also available.
Long term cosmetic help
When electricity is used to destroy hair cells and remove hair permanently. However, it takes many treatments over a long time, it can be painful and may cause scarring or changes to your skin colour (check the electrologist is accredited through the British Institute & Association of Electrolysis).
Involves powerful beams of light (lasers) which destroy the hair. It can last several months and is more effective on women with pale skin and dark hair.
From this week Dr Hilary Jones will start looking at illnesses and conditions that people are secretive about. This week we take a look at varicose veins.
