The dark dye melani in the hair absorbs the energy of the light flashes from the high frequency laser, causing the hair roots to become desolate. At the same time, the hair that is in the growth phase at the time of the treatment responds and falls out.
For flawlessly smooth skin, laser hair removal takes time and several sessions, possibly at intervals. And that’s because: During laser hair removal treatment, only those hair roots that are in a growth phase at this time can be treated. Experience has shown that this is 20 to 30 percent of all hair per session. The rest are currently taking a break during a transition or rest phase. After about four to ten weeks, another part of the hair roots becomes active and can be treated. As a rule, around six to eight laser hair removal sessions are required to catch as many hairs as possible in their growth phase.
It sounds unimaginable that no hair will grow in the lasered areas for the rest of your life. But it’s actually like this: the hair roots that were damaged or destroyed by laser hair removal are inactive. So hair no longer grows from them. However, there are hair roots under the skin that may not be producing hair and may be in a resting phase at the time of the laser hair removal treatment. These cannot be detected during the procedure. It is therefore possible that isolated hairs sprout from these hair roots over time. It can also happen that hair roots that were never active before become active during hormonal changes, for example during menopause or pregnancy. In these cases, further laser hair removal sessions can and should be carried out.
It’s not just the staggered growth of the hairs that lays a role in the number of treatments. Personal type also influences the result. The lighter the skin and the darker the hair, the better and faster the result. In other words the greater the color contrast between skin and hair color, the more effectively the laser can work. White, gray and very light hair cannot be treated because they lack the pigment melanin. This way the laser cannot find the hair root.
Different areas of the body can be permanently depleted with the laser, the cheeks, the chin or the upper lip, the armpits, legs and the intimate area. Be careful near the eyes laser hair removal must not be carried out too close to the eye or below the eyebrows, nor in the fontanel area of the head or on areas of skin that have been tattooed or treated with permanent make-up. Also to be avoided are birthmarks, moles and injured skin areas.
If you are a DIY-type, you can also do hair removal at home using a laser device. Of course, the devices aren’t as powerful as those you will find in a dermatologist’s office. But it’s best to have it done by a professional. The key to any procedure is to know how to deal with possible complications. Dermatologists are the skin experts and are best suited to minimize and manage possible risks.
Lasers are not to be trifled with. That’s why dermatologists recommend carrying out the treatment at a time when the body is not exposed to too much sunlight. The best time for laser hair removal is whenever your skin tone is lightest, and for most people that’s winter. Because the laser targets the melanin pigment in the hair follicle, it can also attack the melanin pigment in the skin. If you have just been on vacation and have gotten a little tan, you should postpone the laser treatment.
So your skin reacts to everything. Don’t worry you can probably still get laser but it’s important to make sure the laser won’t irritate your skin. Especially for patients with sensitive skin, it is advisable to test the treatment on one spot beforehand. For sensitive patients, it may be necessary to reduce the energy of the laser without compromising the benefit, especially in the first few sessions when the hair density is greater.
You have informed yourself, determined that you are suitable and made an initial appointment for laser hair removal. Before you enter the practice, you should understand what is going on in your body. Are you menstruating? It may be better to postpone your laser hair removal treatment until after or before your next period, as the body can be more sensitive to pain during this time. Try to drink plenty of water before your laser hair removal session. Also pay attention to what you we
What you do after laser hair removal is also important. Dermatologists say that sun protection is a crucial factor for skin care. After a laser hair removal treatment, it is important to protect yourself from UV radiation and use a mild soothing cream. Dermatologists suggest using an aloe-based product. Aloe vera but also turmeric, squalene and hyaluronic acid are useful ingredients, but some people may get a darker spot that will heal. The advice about sun protection also applies to people with a lot of melanin. Skin is more susceptible to ultraviolet and visible light immediately after laser hair removal sessions. If there is prolonged redness or skin irritation after the procedure, consider a mild topical corticosteroid cream to quickly reduce inflammation and lower the risk of hyperpigmentation. If you notice that your skin feels a little irritated after the laser hair removal session, there is no need to panic. Swelling around hair follicles is completely normal after treatment, but if it is severe it can be uncomfortable and itchy. Immediately after laser hair removal aftercare, a hydrocortisone cream can be applied to soothe irritated skin. Also make sure your dermatologist uses a cooling gel during the laser hair removal treatment to avoid overheating the skin.

Most people describe the sensation as a light snapping or stinging feeling, similar to a rubber band against the skin. It can be slightly uncomfortable, especially in sensitive areas, but modern devices use cooling systems that make the treatment much more tolerable.
After completing the recommended 6–8 sessions, many people enjoy smooth skin for years. However, some maintenance sessions may be needed once or twice a year, especially if new hairs appear due to hormonal changes.
Laser hair removal is not recommended during pregnancy. There is no evidence that it is unsafe, but because hormonal changes can affect hair growth and there are no long-term safety studies, dermatologists advise waiting until after pregnancy.
Modern lasers are much more advanced and can safely treat a wider range of skin tones than older devices. However, the best results are still seen with lighter skin and darker hair, since the laser targets pigment (melanin). Darker skin types may require more sessions at lower energy levels to reduce risks.
No, waxing or plucking should be avoided, as they remove the hair root that the laser needs to target. Shaving, however, is allowed and even recommended before each session, because it keeps the follicle intact while making the surface hair short enough for the laser to work effectively.
It’s possible, but not ideal. After laser treatment, your skin is more sensitive to UV light, and sun exposure increases the risk of burns and pigmentation issues. That’s why dermatologists usually recommend starting treatments in autumn or winter, when your skin is naturally lighter and less exposed to the sun. If you do it in summer, strict sun protection with high SPF is absolutely essential.
