Laser Hair Removal – What You Should Know
Laser hair removal is a revolutionary treatment in the cosmetic industry. But before you jump into this, it’s crucial to have a clear understanding of what it entails. From different skin types to various laser types and the number of sessions required, there are several factors to consider when embarking on your laser hair removal journey. In this article, we will look into all the essential information you need to know about laser hair removal.
Skin Types and Laser Hair Removal Interact
Understanding your skin type is crucial if you are seeking laser hair removal. Different skin types react differently to the laser’s energy. Therefore, using the wrong laser can lead to ineffective results or even harm the skin.
The Fitzpatrick scale categorizes skin into six types based on its response to UV radiation. Type I represents fair skin that always burns but never tans, while Type VI refers to deeply pigmented dark brown or black skin. An interesting fact is that lighter-skinned individuals tend to respond better to laser hair removal than those with darker complexions.
The four main types of lasers commonly used for hair removal are Ruby, Alexandrite, Diode, and Nd:YAG. Each laser targets a specific pigment in the hair follicle, but their interaction with different skin types varies.
Ruby
Ruby lasers have a short wavelength that is highly absorbed by melanin in fair to light skin tones. This makes them ideal for individuals with light skin and dark hair.
Alexandrite
Alexandrite lasers work well on lighter to olive skin tones and target a wider range of hair colors compared to Ruby lasers.
Diode
Diode lasers have a longer wavelength that allows them to penetrate deeper into the skin, making them suitable for darker skin types.
Nd: YAG
Nd: YAG lasers are unique as they can be used on all skin types due to their longer wavelength that bypasses melanin absorption.
Number of sessions
Human hair growth is divided into three phases, anagen, telogen, and catagen. Laser can effectively target the hair follicles during the early anagen phase when hair follicles are actively growing. But it always needs several sessions to completely destroy the follicles step by step. For this reason, at least 8 treatments are necessary for the best output. Skipping or delaying treatments can result in additional sessions being needed later on.
It is also suggested that there should be a three to eight weeks gap between each session. Along with that, the number of sessions necessary may vary depending on individual factors such as hair color, thickness, and skin tone. While it may seem like a lengthy process, each session brings you closer to achieving permanent hair reduction.
Is laser hair removal permanent?
The answer is no. Laser hair removal is often touted as a long-lasting solution to unwanted hair. This procedure can significantly reduce hair growth and offer prolonged periods of smooth skin. But there is no guarantee that laser hair removal will permanently eliminate every single hair follicle.
This treatment is considered the dormant period of the hair follicles. After undergoing laser treatment, it is common for some follicles to enter a dormant state rather than being entirely destroyed.
These dormant follicles may eventually become active again and start producing new hairs. Regrowth tends to be slower and less noticeable compared to before the treatment, but it is always longer than shaving or waxing.
Costs of Laser Hair Removal
According to the American Society of Plastic Surgeons (ASPS), the average cost per session is reported to be around $400-$500. However, this figure can vary depending on factors including:
- Size of the treatment area
- Number of treatment sessions
- Geographical location
- Clinician expertise
- Type of laser technology
Recovery and Risks
Recovery after laser hair removal is usually quick and relatively painless. However, some common side effects can occur, such as redness, swelling, and skin sensitivity in the treated area.
These symptoms typically slacken within a few hours to a couple of days. Dermatologists often recommend applying cool compresses or using over-the-counter hydrocortisone creams to promote healing. It is also recommended to avoid sun exposure and heat sources for at least 48 hours post-treatment.
One of the potential risks of laser hair removal is skin irritation. While this treatment is effective in removing unwanted hair, it can also cause redness, swelling, and discomfort in the treated area. This is particularly true for individuals with sensitive skin or those who have undergone multiple sessions.
Another risk associated with laser hair removal is pigment changes. The laser targets dark pigment (melanin) in the hair follicle, which can result in a temporary lightening or darkening of the surrounding skin. In some cases, these pigment changes may be permanent and more noticeable in individuals with darker skin tones.
Why follow-up sessions are needed
Every medical treatment goes through multiple follow-up sessions to evaluate the outcome of the treatment. Because these sessions help to assess the patient’s condition, treatment area, and medication planning.
Follow-up treatments help address stubborn or regrown hairs that were missed during previous sessions. Besides, it helps to inspect the treatment area for any complications that may become severe in the future.
Wrap Up
Laser hair removal has revolutionized the way we approach unwanted body hair. There is no doubt that laser hair removal is a highly effective and popular method for achieving long-lasting hair reduction. It offers numerous benefits such as precision, speed, and minimal discomfort. However, it is important to consider factors like skin type and hair color. Consulting with a qualified professional can help ensure a successful outcome.
