Length of Time Between Laser Hair Treatments

In general, the best way to approach this topic is to use the regrowth of hair in the treated area as your guide... in other words, when a significant percentage of the hair starts growing back, return for the next treatment.

It could be as short as 4 weeks on the face, and as long as 12 weeks for the legs or more.

I hope this helps. Take care.

Laser hair removal can be a very effective procedure, but can also be somewhat variable.  You are right in saying that you want to have the treatment performed when the hair is in the growth phase.  This growth phase can differ from patient to patient and between different body areas of the same patient.  For the face, the the wait time between sessions is usually about 4 weeks, while for the body, the approximate wait time is 6-8 weeks.  But the key is to find when your own hair is in the growth phase and return at that point.

Hello and thank you for your question. Sessions are typically scheduled in 4 weeks for facial areas and 6-8 weeks for other areas of the body. Results vary from patient to patient. 

Depending on the area you are treating, hair grows at different rates than other parts of your body. Typically the face tends to grow much quicker than the lower half of the body. We would recommend spacing your treatments 4 weeks apart for the face. As for the rest of the body we would recommended coming every 6 weeks as it does grow much slower. Laser targets active growing hair, every patient is different which is why some clients may have to get a few touch ups at the end of a laser hair removal series. Hope this helps!

I typically have patients do every 4 weeks for the first 3 times and then every 4-6 weeks for 3 times after. It will take a series of treatments and some people need treatments to maintain. See an expert in laser hair removal for best results. Best, Dr. Emer

The laser hair growth cycle is different in different areas and different individuals.  Since the laser is most effective in the anagen phase, treating laser hair more frequently than  a patient's hair cycle is not advantageous.  Almost all areas require at least 3, preferably 4 week interval between treatments so that the hair can shed  from the previous treatment and that the hair will be in the growth phase of hair removal.   

Most people do well with treatments every 4-6 weeks, it is important to space out treatments to allow for skin to heal and to catch hairs in the growth phase which is when laser treatments are most effective.

For the face, 4-5 weeks between treatments, from the neck to waist, 6-8 weeks, and from the legs down, 8-12 weeks.  The further along in treatments, the longer you will have to wait.

As has been pointed out by other practitioners, it depends on the area of the body.  When treating multiple areas (face, underam and bikini on the same day) we stick to approximately 6-8 week intervals.

If the laser is done on upper lip, chin or any area on the face it should be spaced out 4-6 weeks apart. For the body areas, it should be repeated every 8-10 weeks. Facial hair grows faster than lower body hair and it should be done more often. In order for the laser to be effective, you should try to keep up with your appointments and follow the technician's recommendations for the length of time between your treatments.
