A great number of us who dreamt of a hairless body have had laser hair removal therapies as a rescue. The good news is that it truly fulfilled our desire and made us feel good about our bodies till we wake up one day and notice the hair returned. Well, whether you like it or not, laser therapy is not permanent and the pace at which the hair regrows relies on many different elements, for example, the skin, the hair color, and the hair development cycle.

Reasons & Factors for Hair still growing after laser hair removal
Lifecycle of Natural Hair Growth
You must first realize that your hair has a growth cycle that is not influenced by laser therapies. This hair development cycle is divided into three phases: anagen, catagen, and telogen. The growing phase is Anagen, following which Catagen is a transition phase and finally, Telogen is a resting or sleeping phase. Approximately 20% of your follicles are in a growing phase at any given moment. Laser hair removal treatments operate by producing light waves that generate heat. These light waves are only absorbed by dark pigments of the hair called melanin, which eventually heats up hair follicles and damage follicles during the anagen phase of the hair development cycle. Your follicles are in charge of producing new individual hair. When they are injured, they are unable to generate new hair. As a result, surviving hair follicles in the catagen and telogen phases are unaffected by the laser can cycle back to the anagen phase and generate new hair strands. The rate at which hair grows back varies from person to person.
Taking Hair Supplements
If you began taking vitamins for healthier and thicker hair, I am sure you will be pleased with the results. The only difference is that these vitamins cause hair to grow all over your body, not only on your head, as you may have guessed. That isn’t to say that supplements and laser treatments can’t coexist. However, if you’ve paid for a laser package and are also taking hair growth supplements, you may need a few more sessions—or simply accept the reality that your results may never reach the “living hair-free life” stage.
Your body’s hormones will alter throughout pregnancy. And androgenic is one of the hormones that rise during pregnancy. This hormone shift affects where hair develops on the body, leading it to sprout in unexpected areas where it has never grown before, such as around your belly. The hair growth cycle is also accelerated by rising levels of another hormone, testosterone. You may discover that the hair on your body is thicker. There may also be changes in texture and color.
Another thing that affects your hair development during pregnancy is the supplements you use.
The Laser Intensity
Low fluence or energy therapy may cause hair regrowth. Further explanations can be found in the photo-thermolysis theory. The hair follicles are damaged when heated at 65 degrees, while anything below this might lead to increased hair growth. During treatments, the hair follicle often barely touches 45 degrees, and that is the temperature at which hair is stimulated. So the question would be why laser experts or professionals don’t do treatments in 65-degree temperatures? The answer is fast heating. While effective, It can be quite hot and technicians usually terminate the treatment when the patient begins to become a bit uncomfortable.
Different Laser Categories
All lasers are not similar, and the ideal laser for you should be selected depending on your skin type. Alexandrite lasers, for example, are good for those with light skin tones and are believed to pain somewhat less than other types of lasers. However, because the laser’s wavelength is shorter, it doesn’t penetrate as deeply, and as a result, it doesn’t hurt as much. Diode laser therapy is another option. They have a longer wavelength, which allows them to penetrate the skin more deeply. For people with courser hair and medium-dark skin tones, laser diode therapy is extremely successful. It can now be a nearly painless operation because of technological developments. The Nd and LP Nd: YAG laser is a powerful laser. It is more effective on thicker and coarser hair. This is also the ideal kind for people with darker complexions. In reality, it is less effective for those with lighter complexion and finer hair, so they should choose another laser therapy. Of every kind of laser therapy, Nd and LP Nd: YAG treatments have the longest wavelength and therefore penetrate more deeply into the skin, also they tend to be a bit more uncomfortable than other types. However, a visit with a professional should assist you in making your decision.
Your body is undergoing significant hormonal changes throughout menopause, which might explain why hair grows back after laser treatment, particularly on the face. Women who use HRT(Hormone Replacement Therapy) treatment to alleviate symptoms of menopause may also experience a re-growth of hair following a laser on their body.
The way your body creates and processes hormones when you are overweight can contribute to the development of hair by excess weight. Estrogen, for example, can be generated in peripheral fat deposits. These extra hormones can actually stimulate testosterone production, causing hair growth, by disturbing the equilibrium.
Laser hair removal is a safe and efficient method for the treatment of undesirable body hair, although not without risks. An unusual, nevertheless dramatic adverse impact of laser hair removal is an increase in hair density, color, or roughness in the absence of any other recognized causes of hypertrichosis at or near the treated areas. This condition is referred to as paradoxical hypertrichosis, terminalization, induction, and excessive terminal hair growth. Hair induction occurs at the start of laser hair removal after 2-3 treatments. This suggests that hair induction is a gradual process that necessitates some form of local activation. It most commonly happens after vellus hair treatment from the face and neck even though the total hair count in the treated region is decreased, thicker, longer, and more pigmented hairs sprout where the vellus hair previously existed.
Another important element in facial hair development currently acknowledged is intense or persistent stress. Stress and the rise in testosterone both can cause acne, but they can also encourage hair growth.
How long does it take for hair to stop growing after laser?
