7 Ways Your Hair Growth Cycle Affects Permanent Hair Removal

7 Ways Your Hair Growth Cycle Affects Permanent Hair Removal

Hair Removal: The Growth Cycle Matters

  • Hair goes through cycles of growth, transition, and rest. Understanding these phases is key for effective laser hair removal.
  • The anagen (growth) phase is prime time for laser treatments. The laser targets and disables actively-growing, pigmented follicles.
  • Catagen is a brief transition when the hair detaches from its root. Lasers can’t effectively treat hairs in this stage.
  • Telogen is the resting phase when follicles are dormant. Again, laser removal won’t work during this time.
  • Multiple sessions spaced 4-8 weeks apart are needed. This allows targeting follicles in different growth stages.
  • Areas like the underarms may require treatments every 4 weeks. The face may be every 8 weeks due to slower cycles.
The table outlines six crucial factors impacting hair removal results, including hair color, skin type, treatment area, the method used, hair growth cycle, and aftercare, each with a brief note on their specific impact or requirements for optimal outcomes.
Factors Affecting Hair Removal Results


In my decade-long career in the aesthetics industry, one of the most common questions I get asked is about permanent hair removal. Many people are curious about how the hair growth cycle affects the effectiveness of treatments like laser hair removal or electrolysis.

From my interactions with clients at Wellaholic and industry experts, I’ve learned that understanding the hair growth cycle is crucial for achieving optimal results.

In the rest of this article, I will provide more details on the seven key ways your hair growth cycle impacts permanent hair removal treatments.

the number of treatments required to get the best results from laser hair removal can vary from person to person. This is because each hair has its own growth cycle, and multiple treatments are needed to target all of the hairs in the treatment area.

Understanding the Hair Growth Cycle

Hair grows in cycles. Each strand goes through three phases – anagen, catagen, and telogen.

The anagen phase is the growth phase. It lasts two to seven years. During this time, the hair grows about a centimeter every 28 days.

The catagen phase is a transition phase. It lasts two to three weeks. The hair follicle shrinks and detaches from the root.

The telogen phase is the resting phase. It lasts around 100 days. At the end, the hair falls out. A new hair starts the growth cycle again in the same follicle.

Most of us have around 100,000 hair follicles on our scalp. At any time, 90% are in the anagen phase and 10% in the catagen or telogen phase. Knowing this cycle helps manage hair loss better.

The Different Phases of the Hair Growth Cycle

The hair growth cycle consists of a series of events that occur in the scalp over a period of time. It comprises various phases, each with its own goals and requirements for the hair follicle.

  • Anagen Phase. The anagen phase is the active growth phase of the hair follicle. During this phase, the hair grows continuously.
  • Catagen Phase. The catagen phase is a transitional phase when the hair follicle begins to shrink and hair growth slows down.
  • Telogen Phase. In the telogen phase, the hair follicle enters a resting state, and the hair strand is no longer actively growing.
  • Exogen Phase. The exogen phase involves the shedding of the hair strand, making way for a new hair strand to grow in the next anagen phase.
The anagen stage is also the only point where the hair follicle remains attached to the bulb and the laser’s light can disrupt future growth properly.

Way 1: Anagen Phase Targeting – The Best Time for Zapping Away Unwanted Hair

Since every hair is on its own cycle, and laser mainly works in anagen, this is why multiple sessions are needed to catch each hair at the right time. For most areas, I recommend treatments every 6–8 weeks. The face may need more frequent sessions every 4–6 weeks. Legs can be spaced out more to every 10–12 weeks.

Most of my clients need at least 6–8 sessions to see a significant permanent reduction in hair. With each treatment, we’re disabling more and more follicles. The hair that does grow back becomes finer and sparser. After completing a treatment package, I have them come back for occasional touch-ups to stay smooth.

While it’s a process that requires some patience, the end results are absolutely worth it. By timing the treatments to target hairs in anagen, laser provides the most effective and longest-lasting hair removal. I love helping my clients at Wellaholic finally get rid of their unwanted hair with a customized treatment plan.

By targeting the hair follicle with high-powered lasers, laser hair removal can effectively destroy the hair at its root, preventing it from regrowing for weeks, months, or even years.

Way 2: Ineffectiveness of Hair Removal on Dormant Phases

Hair removal is a common aesthetic treatment. But many don’t realize its ineffectiveness during dormant phases. Let me explain.

Hair has growth cycles – anagen (growing), catagen (transition), and telogen (resting). Hair removal only works on anagen hairs. Telogen hairs are dormant and unaffected. They’ll eventually shed, with new anagen hairs replacing them.

So hair removal gives a temporary smooth look. But those dormant telogen hairs remain. Once they enter anagen, new growth appears – often within weeks for areas like the face. That’s why regular treatments are needed for lasting smoothness.

The key is timing treatments when more hairs are in anagen. An experienced professional can guide you on the ideal frequency based on your hair cycle and areas treated. With proper scheduling, you’ll maximize results and minimize discomfort from excessive hair removal.

As we’ve learned, laser hair removal is most effective during the Anagen phase, the active growth phase of the hair cycle. However, not all hairs are in this phase at the same time. This means that to effectively target all hairs, multiple sessions spaced out over a certain period are necessary.

Way 3: Timing of Hair Removal Sessions

I get a lot of questions about the best time for hair removal sessions. The truth is, there’s no one-size-fits-all answer. It depends on your hair growth cycle and personal preferences.

For example, some people prefer to get waxed every 4-6 weeks when the hair is long enough. This allows for a smoother result that lasts longer. Others opt for laser hair removal every 6-8 weeks to catch the active growth cycle.

My advice? Listen to your body and pay attention to your hair growth patterns. If you’re unsure, consult with a professional aesthetician. They can assess your individual needs and recommend a personalized treatment plan. The key is finding a routine that works for you and sticking to it consistently.

contrary to popular belief, your hair has a life cycle of 2-6 years, and it drops out. And a new hair grows in its place, just like how plants grow in nature.

Way 4: Individual Variations in Hair Growth Cycles

Hair growth is not a one-size-fits-all process. Each person’s hair has its own unique cycle. This cycle consists of three phases: anagen (growth), catagen (transition), and telogen (resting).

The length of each phase varies from person to person. Some people have longer anagen phases, resulting in longer hair growth before shedding. Others have shorter anagen phases, leading to more frequent shedding and shorter hair lengths.

I’ve seen clients with different hair types and growth patterns. For example, a client with fine hair may experience more frequent shedding compared to someone with coarser hair. Factors like age, hormones, and genetics also play a role in determining an individual’s hair growth cycle.

Understanding your hair’s unique growth pattern is key to developing an effective hair care routine. Be patient and work with a professional to find the right products and treatments for your specific needs.

Hair density, which refers to the number of hair follicles in a given area of your skin, is a significant factor in hair removal.

Way 5: Hair Density and Regrowth

I know hair loss is a big concern for many. It can be stressful and impact self-confidence. But there are solutions to improve hair density and regrowth.

When I was starting out, I had a client who came in feeling really down about her thinning hair. We did a consultation and I recommended a laser hair regrowth treatment plan. After several sessions, her hair started looking fuller and healthier. She was so happy with the results!

The key is being consistent with the right treatments. Laser therapy stimulates the follicles and can help with regrowth. Combining it with products like minoxidil can give even better results. Of course, it’s important to address any underlying causes like hormonal imbalances or nutrient deficiencies too. With some patience and the proper plan, you can absolutely see an improvement in hair density over time.

Way 6: Effectiveness of Different Hair Removal Methods

As an aesthetic director, I often get asked about the best hair removal methods. There’s no one-size-fits-all solution, but here’s my take based on experience.

Shaving is quick and convenient for areas like legs and underarms. But the results are short-lived, and you risk nicks, ingrown hairs, and irritation if not done properly. Waxing gives longer-lasting smoothness, around 2-3 weeks. But it can be painful, especially for sensitive areas. Epilation or threading are longer-term options that pluck hairs from the root. They require some pain tolerance too.

For more permanent reduction, laser hair removal is highly effective when done right. It targets and disables hair follicles with laser light energy. The key is going to an experienced professional and committing to multiple sessions for optimal results. It’s an investment, but worth it if you want to be fuzz-free for good.

After treatment, avoid sun exposure and use sunscreen. Don’t exfoliate immediately; let your skin recover. Multiple sessions may be needed to catch all hairs in the Anagen phase.

Way 7: Pre and Post-Treatment Care

Understanding your hair growth cycle can improve your hair removal results. Hair has three phases: Anagen (growth), Catagen (transition), and Telogen (resting). Treatments like IPL and laser hair removal work best in the Anagen phase.

Before treatment, avoid waxing or plucking for a month as these methods remove hair from the root, making it harder for the laser or IPL to target the follicle. Shaving is recommended as it removes surface hair but keeps the follicle intact.

After treatment, avoid sun exposure and use sunscreen. Don’t exfoliate immediately; let your skin recover. Multiple sessions may be needed to catch all hairs in the Anagen phase.
