Underarm Laser Hair Removal: What to Expect?

Underarm shaving can be an aggravating task if you do it every few days. Underarm hair removal is more challenging than it sounds due to razor burn, ingrown hairs, stubble, dark looking hair follicles, and frequent maintenance. Waxing also offer a smoother appearance for longer periods of time but still requires repeat appointments and regrowth of hair in between services.

Underarm laser hair removal is more long-lasting because it utilizes selective laser energy focused on the melanin in the hair follicle. Controlled thermal injury to follicular structures related to hair growth following absorbed energy leads to progressive decrease in regrowing hair amount and thickness.

One of the most frequent sites of hair removal is the underarms. The area is not too large, the hair is darker and thicker than other body hair and can be treated relatively quickly. Laser hair removal at Enfield Royal Clinic in Tomball, TX is recommended after a consultation. The appropriate treatment approach is determined after taking into account such factors as skin tone, hair type, medical history, treatment goals, and other individual factors.

Why Do Underarms Respond Well to Lasers?

Underarm hair is a good target for laser hair removal treatments as it is coarse, dark, and relatively thick when compared to very fine facial or body hair. Selective photothermolysis is the basis of laser hair removal, where the laser wavelength is absorbed by a certain chromophore, hair melanin. The heat produced by this process moves towards the follicular components and can harm the cells that produce hair.

Dark, coarse hair has more melanin and absorbs more laser energy than very fine or lightly pigmented hair. The problem with blonde, gray, and white hairs is that there is little pigment to target with the laser, and they typically don’t react to it as well as darker shades. Laser hair removal has been specifically studied in the area of the axilla. 755 nm Alexandrite and ~800 nm diode lasers provide significant long-term hair reduction after multiple treatments.

Each laser technology is selected depending on the patient’s skin tone and hair qualities. 

The choice of this setting is especially significant as it can lead to burns or pigmentation if set incorrectly. Laser hair removal must be done on all skin tones with proper precautions and expertise.

Session Length & Count 

Underaram Laser Hair Removal is a fairly small and less time taking procedure. The actual duration varies according to the laser platform, spot size, treatment parameters, hair density and other areas being treated. During the treatment, the physician cleanses the area under the arm and positions the skin properly, before delivering laser pulses. Patients report warm pinpricks, snaps or a feeling like a rubber band.

A cooling system helps in protecting the epidermis and enhances the comfort. Following this, some patients experience the skin becoming warm, red, swollen, and slightly tender.

Typically, laser hair removal does not take place in a single session. The hair follicles are in a cycle of hair growth, anagen, catagen, and telogen. Laser hair treatment is most effective when the targeted hair is in the appropriate active growth phase, which means that more than one treatment is required to treat the follicles when they are in the right phase.

Many patients require about 2 to 6 treatments, but the amount of treatments varies for others depending on the treatment area, hair type, skin type and the treatment effectiveness. Most patients get treatments every 4–6 weeks, depending on the time the physician chooses.

Repeated treatments cause underarm hair to become finer and less dense. Occasional maintenance sessions are needed over time if regrowth is seen. It is important to consider laser hair removal as a long-term hair reduction, not a definite hair removal in a certain number of sessions. Results differ from person to person and hormones play a role in future hair growth.

Pre-Appointment Preparation of Underarm Laser Hair Removal

Preparation for Underarm laser treatment is an important part to minimize the risk of irritating the skin and establish a secure treatment environment. Your physician should provide you with detailed recommendations according to your skin and treatment. General preparation consist of:

  • Do not tan: Recent tanning causes an increase in the amount of epidermal melanin and leads to more pigmentary complications. The American Association of Dermatology advises not to get tanned prior to laser hair removal.
  • Avoid waxing or plucking: Waxing and plucking hair from the follicle leaves less of the target structure to be treated by the laser.
  • Shave as per provider’s instructions: Shaving removes all hair above skin level, but leaves the target under the skin.
  • Clean skin: Deodorant, antiperspirant or lotions, oils or other products must be removed prior to treatment.
  • Prevent unnecessary irritation: Do not come with freshly irritated, ripped or inflamed skin under the arm.
  • Notify pharmacists of medications: Inform your health care professional of any prescription medicines, over-the-counter drugs, supplements or skin care products.
  • Tell your provider about any past reactions to lasers: Let your physician know if you’ve had any laser treatments in the past, or history of abnormal scarring, pigmentation issues, or any other skin reactions.
