How Does Laser Hair Removal Affect Hair Growth?
Hair does not all grow at the same time. At any given moment, some hairs in an area are actively growing, while others are resting or getting ready to fall out. A laser generally works best on hair that is in its active growing phase, because that is when the hair follicle holds the most pigment for the laser to target. This is one reason a single session cannot treat every hair in an area at once. Sessions are usually spaced several weeks apart so that hair which was resting during one visit has time to move into its active phase before the next one. Over a full series, this approach is meant to catch more of the hair in an area than one session alone ever could.
How Many Sessions Will I Need?
There is no set number of sessions that works for everyone, since several things influence how hair responds to treatment. Hair color, hair thickness, skin tone, hormones, and the area being treated can all change the outcome. Coarse, dark hair often responds differently than hair that is naturally fine or light, and smaller areas like the face can behave differently than larger areas on the body. Because so many factors are involved, we do not promise a fixed number of sessions ahead of time. Your provider looks at your hair and skin in person and talks with you about what a reasonable plan may look like for your specific situation before anything is scheduled.
What Areas Can Be Treated?
At Pearl Med Spa, laser hair removal is offered for facial and body areas. The approach that makes sense for one area is not always the same as the approach for another, since hair density and skin sensitivity can differ depending on where an area is located on the body. Some areas may also respond faster than others, though this varies from person to person. If you are interested in a specific area, your provider can go over what makes sense for you at your consultation.
Why Does Some Hair Come Back Over Time?
Hormonal changes, new hair follicles, and natural shifts in the body can all bring on some new hair growth over time, even after a full series of treatments. This can happen months or years later, and it is considered a normal part of how hair works, not a sign that anything went wrong with earlier sessions. Life changes such as pregnancy, certain medications, or shifts in hormone levels can also affect hair growth in ways that have nothing to do with the treatment itself. If you notice new hair growth after finishing a series, that does not mean the earlier sessions failed to do what they were meant to do. Your provider can talk with you about what to expect for your specific hair and skin at your consultation.
Will laser hair removal remove all my hair for good?
Laser hair removal is meant to reduce hair growth over time, though it does not promise that hair stops growing forever. Results vary by person, and some fine regrowth is common years later because of hormones and other factors.
How many sessions does laser hair removal usually take?
The number of sessions needed varies by hair type, skin tone, and treatment area, so there is no single number that fits everyone. Your provider sets out a plan that fits your hair and skin at your consultation.
Does laser hair removal hurt?
Comfort during a session varies by person and by the area being treated. Your provider can talk you through what sessions are generally like and answer any questions at your consultation.
Can I get laser hair removal on my face and body?
Yes. Laser hair removal is offered for facial and body areas. Your provider can help you figure out which areas make sense for your goals at your consultation.
How much does laser hair removal cost?
The cost is set at your consultation, since it depends on the areas you want treated and how many sessions make sense for your hair and skin.
