If you have problems with ingrown hairs, then try a home program that consists of exfoliation and keeping your skin very hydrated. Also very important is cleansing the skin with a hospital-grade antiseptic to prevent any type of breakout which can proliferate into an ingrown hair. You should avoid using loofahs or other abrasive things immediately after waxing, and afterward, you must use sunblock with at least SPF-15. Also, avoid extreme heat like jacuzzis, steamrooms or saunas right after waxing. For permanent hair removal, electrolysis is the only thing that has been able to claim those results right now.
Lasers can claim permanent hair reduction.
People will have regrowth with laser hair removal, but right now only electrolysis is considered permanent. There are different types of lasers out there, and the amount of time the session lasts depends on the area you're having done. The results last about six weeks to three months. People with blonde or gray hair are not good candidates for laser hair removal. People with darker skin pigments can not be treated with most types of lasers, so tanning before a laser treatment is a big no.
