What are the side effects of electrolysis? And does laser hair removal work on fine hair?

you can sometimes get small burns, open pores must be kept clean as you can get spots also.

Hi Abi
If carried out by an experienced electrologist,there are no side effects.There can be some slight redness for a short time after treatment,and on very odd occasions there may be a slight bruise,but this is usually on more mature skins.I have been working in this field for nearly 30 years and it is a safe and regognised permanent method of hair removal.
Laser hair removal will treat fine hairs,but there is difficulty if the hairs lack pigment ,such as grey/white hairs or very blonde hair.Also if the skin pigment is very dark (darker than the hairs,the laser is attracted to the darker pigment) and therefore can cause prob;ems.
Check out you local are for experts in both fields, for a free consultation and then decide on which will work best for you.Good luck.
