The quack claims for laser hair removal treatment

"Painless" or "Virtually Painless"

Overall, laser hair removal is not pain, but the patient is uncomfortable. It feel like a rubber band snapping the skin. Of cause it is also dependant upon your pain threshold and skin or hair type. The hurt is less for people with lighter skin tones and finer hair

"Permanent " or "100% Permanent"

The facts : There is no 100% guaranteed permanent for laser hair removal. It can reduce hair counts 40% to 80% even ideal candidates with light skin and dark hair.
As to date, there is no laser equipment that has been approved by the FDA for permanent hair removal. Hair growing back at some point is still possible, whether it's a reduced amount, finer version, or combination of both.

"Guaranteed 0% Regrowth"

Nobody knows for sure what the regrowth rates are. Some people notice regrowth after several months or years, while others find they never have to hair removal again. The average experience is 70%-80% reduction in hair growth if you do a full 4-6 course laser hair removal treatment.

"Laser Hair Removal Ahead Of Electrolysis"

It is not always the laser hair removal ahead of electrolysis.

Not all types of skin are suitable for laser hair removal, Electrolysis is generally suitable for all hair and skin types. Electrolysis is the only method of hair removal which has been scientifically proven to result in permanent hair removal, but it is very painful and has the risk scars.
The overall cost of laser hair removal is much lower than electrolysis although the cost per session for laser hair removal is far in excess of that for electrolysis.
