Laser hair removal is used to permanently reduce the hair growth but it may take several treatment sessions before noticing the effect. As hair follicles cannot be targeted at the same time because it grows in various stages. Notice hair shedding in about 10 – 15 days post procedure, few weeks after the treated area becomes smooth, another treatment is necessary. On the other hand, waxing is short-term. All you need is wax and thin piece of cloth. Just spread the wax in the desired area and remove it by spreading thin fabric on it and pull it in a instantly. This will result to hair-free skin for a week or two.
As for the pain, both procedures do not guarantee pain free. However, topical anesthetic is used for the laser hair removal thus lessening the discomfort of the procedure. The pain in waxing especially the first strip is almost unbearable but after your body’s endorphins kicks in pain will be tolerable. But of course, pain is subjective so it varies for each person. The annoying disadvantage of waxing is that it is messy and needs to be done in monthly basis to maintain a smooth and hair-free skin.
Bottom-line is laser hair removal is better in so many ways but it is way more expensive that the waxing.
