Am I a Candidate for Laser Hair Removal?
Both men and women seek laser hair removal services to have unwanted hair removed. Hair removal is commonly done on the hairline, eyebrow, top of the nose, lip, chin, ear lobe, shoulders, back, underarm, abdomen, buttocks, pubic area, bikini lines, thighs, face, neck, breast, arms, legs, hands, and toes. Laser works best on pale skin and dark coarse hair. The closer you are to this combination (i.e. the lighter the skin and the more coarse and dark the hair), the better the results will generally be. At Go Bare our priorities are your safety, health, and results.
What is Laser Hair Removal?
Laser hair removal is a procedure by which hair is removed from the body by utilizing a long pulse laser. Lasers are developed and designed from years of research. The laser parameters are carefully defined by studying the anatomy of the hair follicle and precisely matching the laser light and pulse duration to the follicle size, depth and location to inhibit the re-growth of the hair.
Laser hair removal is performed by a specially-trained laser specialist or a doctor, who distributes the light of a long pulse laser onto the skin. The laser works by disabling hairs that are in their active growth cycle at the time of the treatment. Since other hairs will enter their growth cycle at different times, several treatments are necessary to disable all of the follicles in a given area.
Is Laser Hair Removal Permanent?
The general opinion is that laser hair removal is permanent, and the Food and Drug Administration approved it as “permanent reduction” because it doesn’t work on everyone. Generally, this means that you shouldn’t expect laser to remove every single hair from an area. Some people need to follow up with electrolysis treatments for any remaining hairs for complete clearance as hair becomes too fine for laser to target and you reach diminishing returns. Most will also need touch-up treatments 1-2 times a year after the initial set of treatments for any new growth your body develops with age.
It has also been observed that some people seem to be non-responders – this is not confirmed and reasons are not known as not enough research has been done in this area. Keep in mind that it's also difficult to judge whether someone’s lack of results is due to the person’s potential underlying medical condition that causes continuous growth and makes it seem like laser isn’t working, whether the treatment wasn't performed properly, or whether for some people it just doesn't work and we don't know why. Basically, you can’t determine this for yourself unless you try it. In addition, results also depend on many variables involved.
A set of at least 6-8 treatments at specified intervals are generally necessary to achieve substantial hair removal with the laser. Factors that determine the length of treatment include the particular area to be treated, the texture of hair, frequency of treatments, history of temporary measures to remove hair (waxing, tweezing, shaving, and depilatories), etc
How Does LHR Work?
Lasers are optical devices which produce intense coherent, collimated and mono-chromatic beams of light. A laser consists of an active medium such as a crystal, gas or liquid that amplifies light when excited by an external energy source (a flash amp or electric discharge, for example). When the appropriate medium is employed, the laser can be fine-tuned to generate a very narrow band of light wavelengths (such as the individual colors of the visible spectrum).
Lasers designed for permanent hair reduction emit wavelengths of light designed to be absorbed by the pigment in the hair (melanin). If the surrounding skin is relatively light compared to the color of the hair, then the entire energy of the laser will be concentrated on the hair shaft, effectively destroying it without affecting the skin or follicle. Hair removal lasers target the dark pigment in the hair. That’s why laser hair removal works best on light skin (so the laser passes right through) and dark coarse hair (has most pigment).
The ability of the laser to produce a very narrow bandwidth on a consistent basis is the key to a safe efficient treatment. While the laser emits a beam that only heats the hair shaft, heat is transmitted from the hair shaft to the surrounding tissue for several milliseconds after the laser pulse. Several lasers possess cooling attachments which cool the surrounding skin to fully absorb any heat transmitted from the destroyed hair shafts.
What Should I Expect Before and After Treatment?
You should shave the area to be treated 1-3 days before treatment (some clinics will offer to do this for you, but beware of irritation caused by disposable razors etc). No waxing or removing hair with the root with any other way is allowed 4-6 weeks before and throughout the course of treatment as hair needs to be in place to be targeted by laser. The area should be shaved as closely as possible so that laser can target the most energy towards the hair follicle and not waste energy on the part of the hair above the skin’s surface. If your hair is the type that you can’t see where it was right after you shave, make it a bit easier on your tech not to miss the spots you want treated by shaving 1-3 days before so the outline of where hair is growing is just VERY slightly visible. After treatment is completed (underarms take under 10 minutes, back treatment can take up to 1 hour), you should apply aloe vera to soothe the skin for a few days. Within two to three and a half weeks, you should experience shedding of all treated hair. At first, hair will look like it’s growing back in, but it is just coming through the skin to shed. Shedding starts at about one and a half weeks and can last until three and a half weeks post-treatment. Exfoliating and/or scrubbing gently in the shower with a loofa can help speed up the process. After shedding finishes, you might experience little black dots still “stuck” in the skin. These are commonly referred to as “pepperspots” and will shed eventually, but might take a bit longer. Exfoliate to help those out as well. After shedding occurs, you should experience a hairfree period for a few weeks, until next set of hair that was dormant before starts to come in. Once you have enough to justify one, go in for another treatment. This usually happens within 6-10 weeks post-treatment. Patient continues this process until he/she has reached diminishing returns and the remaining hairs are too fine for laser to target, or until you have reached you desired reduction.
How Many Treatments Will I Need and How Far Apart are They Scheduled?
Most people need at least 6-8 initial treatments spaced 6-10 weeks apart. This is because hair grows in 3 phases and is killed in the first “anagen” active growing phase. Several treatments are needed to target ALL hair in the active growth phase. Approximately 6-10 weeks after every treatment, additional treatment is required to eliminate the hairs that came out of the dormant phase and are now active. After 6-8 treatments or so, patients should experience a considerable percentage of hair reduction. Depending upon hair type and genetic factors, some clients may require additional treatments beyond these initial treatments. If it seems like the treatments are not working after 6-8 treatments, patients should look into possible underlying reasons (see Question #9 below).
Usually, treatments are spaced 6-8 weeks apart to start, and gradually move to 8-10 weeks apart after the initial 2-3 treatments. Instead of following an arbitrary schedule, wait until you have experienced shedding of the treated hairs (should complete within 2-3.5 weeks) and you see enough hair come in after the hairfree period to justify the next treatment.
Is It Painful?
In one pulse, the laser can remove all the hair on a patch of skin the size of a nickel (depending on the specific laser spot size ranging from 9-18mm on average – i.e. the “head” of the laser from which the power is coming with every pulse). Everyone’s pain threshold is different, but generally laser hair removal is not much more painful than waxing, but the sensation is different. It resembles a rubber band snapping against the skin for a quick second with each pulse. Most people do not require an anesthetic cream (like EMLA), but one may be used for very sensitive patients/areas (can be provided or prescribed at the clinic). Be aware that using anesthetic creams is only safe on small areas (like upper lip, bikini, or underarms) and in small quantities. Using it on large areas like the back can cause adverse effects or even death. Consult with your tech and doctor if unsure.
What are Possible Risks and Side Effects?
The possibility exists that some side effects or complications can occur given various variables, including: Normal Itching, during treatment Redness for up to 3 days Swelling (around mouth of follicle) for up to 3 days Pain, tingling, or feeling of numbness (cold spray) Rare Crusting/scab formation (on ingrown hairs) Bruising Purpura (purple coloring of the skin) on tanned areas Infection Temporary pigment change (hypo-pigmentation or hyper-pigmentation) Side effects occur infrequently and, as a rule, generally are temporary. If any of the above last for more than 3 days, make sure to contact your technician and/or doctor. There is a possibility that settings were set too high and the technician needs to know in order to adjust on your following treatment.
What are the Possible Causes of Excessive Hair Growth and How Can It Affect My Treatments?
The causes of excessive hair growth pattern are many and varied, including: Heredity, Pregnancy, Glandular, and/or hormonal imbalances (possible PCOS condition for women), including diseases causing these effects Insulin resistance issues, Reactions to certain medications, Normal aging processes, Excessive temporary removal methods like waxing, tweezing, creams and depilatories, etc. Every laser candidate should explore a possible underlying reason of the extreme hair growth before starting laser because if there is something in the body consistently triggering hair growth, laser treatments might seem ineffective because the body will keep developing new hair. So, it will always seem like there is not reduction, when in fact it’s NEW hair your body is producing that you are seeing, not that treated by laser growing back.
Women with PCOS hair growth patterns (upper lip, chin, cheeks, etc) should see an endocrinologist and have hormonal tests taken. Men can get tested for insulin resistance etc. Talk to your doctor if you suspect you might have an underlying medical condition causing excessive hair growth before starting laser hair removal. Once the condition is control through treatment/medication, laser hair removal can then be performed. Laser can affect the hair that’s currently present, but cannot prevent NEW hair from developing.
What is the Hair Growth Cycle and How Does It Work?
Under normal circumstances hair growth in each hair follicle occurs in a cycle. There are three main phases of the hair growth cycle: anagen, catagen and telogen. Anagen (active) is the growing phase or when the hair fiber is produced. During anagen, the hair contains an abundance of melanin, the pigment which gives your hair its color. This is the phase during which laser hair removal treatment is most effective. Catagen (club hair) is the period of controlled regression of the hair follicle. This phase is when the lower part of the hair stops growing, but does not shed, and the follicle is reabsorbed. It will be difficult for permanence to be achieved when the hair is in the catagen growth cycle. Telogen (tired) is the last of the hair growth cycle. In this resting phase, the old hair falls out in preparation for the development of a new anagen hair. Permanence cannot be achieved when the hair are in the telogen growth cycle. Remember, anagen is followed by catagen, a period of controlled regression of the hair follicle. Ultimately the hair follicle enters telogen, when the follicle is in a so-called resting state. Normally this cycle of hair production will continue for the duration of the individual's life. However, other factors can influence, promote and inhibit hair production. How well the laser can eliminate the hairs, depends on the skin type/color, hair type/color and what initially caused the hair to grow.
Can I Just Reduce the Density of Hair Instead of Removing It Completely?
Yes, this can be achieved with having only a few treatments instead of the complete set of 6-8 and by our experienced technician who is careful not to miss areas during treatments.
