How many treatments are needed ?
Generally between 6 – 8 treatments are required. Don’t expect an immediate result. Approximately 10 – 25% reduction in hair growth can be seen after the first treatment. This is due to the different stages of hair growth and how much energy the hair follicle has received. Hair that grows back will be thinner and generally lighter. It is very important to avoid the sun after treatment as hyperpigmentation can occur and skin is extremely sensitive after treatment and can get burnt. When it is safe to go in the sun ensure that you are well protected with at least a sunblock of 50, applied minimum of twice a day.
Hair growth stages:
There are 3 different stages in the life of a hair.
1) The growth phase – Anagen
2) The resting phase – Catagen
3) The falling out phase – Telogen
Only hair in the Anagen (growing phase) are affected by the laser as the hair is in the follicle and the follicle is closest to the skin during this phase. Thus the laser can target the pigmented hair, reach the follicle, heating it up and destroying it. This is why several appointments are required.
Avoid the following 4 to 6 weeks prior to treatment:
- Hair removal creams
- Sun tanning /tanning beds/tanning creams
