Understanding the hair growth cycle is essential for laser hair removal and other hair removal methods. Hair goes through different phases of growth, which affect laser hair removal treatments; Laser treatment is most effective when it targets hair follicles in the active growth phase.

The hair growth cycle consists of three main phases:

Anagen Phase (Active Growth)

– This is the phase when the hair is actively growing. The root of the hair is firmly attached to the hair follicle, which is anchored in the skin.

– The duration of the anagen phase varies depending on the body area and individual genetics, but it can last several weeks to several years.

Catagen Phase (Transitional)

– The catagen phase is a transitional phase where the hair follicle begins to shrink and detach from the hair bulb.

– This phase is relatively short, lasting only a few weeks.

Telogen Phase (Resting)

– In the telogen phase, the hair is no longer actively growing. It is fully detached from the hair bulb and eventually falls out.

– This phase can last several weeks to a few months.

– New hair starts growing underneath the old one in preparation for the next anagen phase.

It’s important to note that not all hair follicles are in the same phase at the same time. Hair growth cycles are asynchronous, meaning that individual follicles go through the phases independently of one another. Additionally, the length of each phase can vary based on genetics, hormonal factors, and anatomical location of hair follicle.

During laser hair removal, hairs in the anagen stage are an accessible target for laser energy. When the laser is absorbed by the melanin in the hair bulb, it generates heat that can effectively damage the hair papilla, and deactivate the follicle, preventing further hair growth, this is why it’s crucial to target as many follicles as possible during their anagen phase.

However, because not all hair on a given area is in the anagen phase simultaneously, multiple laser hair removal sessions are necessary to target hair follicles as they enter the anagen phase over time.

Treatment intervals, schedule and number of sessions depend on the specific area being treated, medication, ethnicity, hormones, and individual lifestyle factors. For some areas, like the face, treatments may be spaced closer together, while body areas like the legs or back might have longer intervals between sessions.

Consistency with the recommended treatment plan is crucial to achieve long-term hair reduction or removal.

By understanding the hair growth cycle and its phases, laser hair removal specialists can optimize treatment plans to target hair follicles when they are most responsive to the laser, leading to more effective and long-lasting results.

Comparing laser hair removal to traditional hair removal methods.

Traditional hair removal methods such as shaving, waxing, and plucking etc, are temporary solutions. These methods offer quick, but short-term results as hair usually regrows within a few days, to weeks.

Shaving can lead to stubble, rashes, irritation, follicular infections such as folliculitis, and can leave a shadow under the skin. Shaving facial hair can cause stress and anxiety for individuals, particularly women, who experience unwanted or excessive facial hair growth. The fear of hairs becoming visible or the sensation of stubble can be emotionally taxing. Freshly shaved facial hair can sometimes appear darker or more noticeable, particularly if it’s thick or coarse, leading to heightened self-consciousness.

Additionally, frequent shaving can lead to skin irritation, redness, or even razor burn, further compounding the stress and discomfort associated with facial hair management. Because of these issues, dealing with unwanted facial hair can affect self-esteem and self-image, and the daily worry about its visibility can be a source of emotional distress.

Hair removal methods that pluck out the hair, such as waxing threading, epilation and sugaring can be painful and cause ingrown hairs. Repeated use of these methods can result in skin irritation, ingrown hairs, and, in the case of waxing, occasional burns. They also present a unique discomfort during the period leading up to the removal appointment, as the hair has to be left to grow to the optimal length for treatment.

Laser hair removal

Laser hair removal is a non-invasive procedure meaning it does not involve surgical incisions or significant trauma to the skin. This reduces the risk of complications and promotes a faster recovery.

One of the appealing aspects of laser hair removal is that it typically involves minimal downtime, allowing individuals to resume their regular activities immediately after the procedure. Most individuals experience a few minutes of flushing in the treatment area that quickly resolves on its own.

Laser hair removal sessions are relatively quick, particularly for smaller treatment areas like the upper lip, underarms, or bikini line. The duration of each session depends on the size of the area being treated, but it takes as little as 3 minutes for areas such as upper lip and chin.

The hair can be shaved between treatments and it is advised to freshly shave the hair prior to treatment.

Although there is no immediate hair loss following a single session, the hair gradually falls out over the weeks following treatment. This allows individuals to continue with their daily routines without significant disruption.

It’s essential to follow the post-treatment care instructions provided by your laser specialist, which may include avoiding hot showers, sun exposure, and specific skincare products for a short period to ensure the best results and minimize the risk of side effects. It is advised to avoid sun exposure and wear sunscreen as a precaution throughout your treatment programme.

In terms of long-term cost and convenience, laser hair removal can be more cost-effective over time as it reduces the need for regular, ongoing maintenance associated with traditional methods.

The choice of hair removal method depends on individual preferences, needs, and skin and hair types. However, when more permanent results are beneficial, laser hair removal treatments are a long-term solution to unwanted hair. Laser hair removal alleviates some of the stress of unwanted hair, and provide more extended periods of smooth skin and reduce the constant concern about hair regrowth. They help individuals regain their confidence and minimize the stress associated with managing unwanted hair.

On average, most individuals require 6+ laser hair removal sessions for a complete treatment. However, this number can vary, and some people may need more, or less, sessions to achieve their desired results. It’s essential to follow the treatment plan recommended by your laser hair removal technician to optimize the outcome.  Even after completing the initial series of treatments, some individuals may benefit from occasional maintenance sessions to ensure that any remaining, previously dormant hair follicles are effectively treated and to maintain the long-term results. Maintenance sessions may be required at 6 monthly+ intervals.

In conclusion, the success of laser hair removal relies on targeting hair follicles during their growth phase and the need for multiple treatment sessions to achieve significant and long-lasting hair reduction. A personalized treatment plan developed by a qualified professional will take into account individual factors and the specific anatomical area to provide the best results.
