How IPL Hair Removal Works – Understanding the Hair Growth Cycle

When it comes to permanent hair reduction, IPL (Intense Pulsed Light) technology has become a popular and effective method. If you're considering using IPL for hair removal, it’s important to understand how the hair growth cycle plays a significant role in the process.

At The Lux Skins, we aim to help you get the best results with your IPL hair removal device. By understanding the stages of hair growth, you’ll be able to optimize your treatments and enjoy smoother, hair-free skin for the long term.

What is IPL Hair Removal?

IPL (Intense Pulsed Light) is a non-invasive, light-based technology that targets the melanin in your hair follicles to reduce and eventually stop hair growth. The light pulses emitted by the IPL device are absorbed by the pigmented hair and converted into heat energy, which destroys the hair follicle’s ability to grow new hair.

How IPL Works:

  • Light energy is absorbed by the melanin in the hair follicle.

  • This energy is converted into heat, which damages the follicle.

  • Damaging the follicle prevents future hair growth in the treated area.

IPL is a safe, fast, and effective solution for long-term hair removal, but it works best when you understand the hair growth cycle and how it affects the results.

The Hair Growth Cycle: A Key Factor in IPL Success

The hair growth cycle consists of three main phases:

  1. Anagen (Growth Phase)

  2. Catagen (Transitional Phase)

  3. Telogen (Resting Phase)

Understanding these phases is critical because IPL is most effective when hair is in the anagen phase, the active growth phase. Let's take a closer look at each phase and how it impacts IPL hair removal.

1. Anagen Phase (Growth Phase) – Best for IPL Hair Removal

The anagen phase is when the hair is actively growing and has the highest melanin content. Since IPL targets melanin, hair in this phase is the most responsive to treatment. This is when IPL works best to damage the hair follicle and prevent future growth.

  • Duration: 2-6 years (depending on the area)

  • Ideal for IPL: Yes, IPL can effectively reduce hair growth during this phase.

  • Result: IPL destroys the follicle by heating the pigmented hair.

2. Catagen Phase (Transitional Phase) – IPL is Less Effective

The catagen phase is the transitional phase where the hair stops growing and begins to shrink. During this phase, the hair follicle detaches from the blood supply, and the hair is prepared for shedding. Since the hair is no longer growing, IPL is less effective at targeting the follicle.

  • Duration: 2-3 weeks

  • Ideal for IPL: Not ideal for hair removal since the hair is not actively growing.

  • Result: IPL treatments may not be as effective because the follicle is no longer in the growth phase.

3. Telogen Phase (Resting Phase) – No Effect on Hair Removal

The telogen phase is when the hair is dormant and is eventually shed, making room for new growth. Because the follicle is not actively growing during this phase, IPL has no effect on the hair. This is the phase where you might notice some hair shedding after treatment, but IPL will not work to prevent future growth at this time.

  • Duration: 2-4 months

  • Ideal for IPL: No, IPL is not effective during the telogen phase because the hair is not actively growing.

  • Result: Hair will shed naturally, but no long-term reduction occurs.

Why Do Multiple IPL Treatments Work?

Because not all hairs are in the same phase at the same time, multiple IPL treatments are required for optimal results. Typically, only about 20-30% of your hair is in the anagen phase at any given time. This is why IPL works best over several sessions.

Typical IPL Treatment Plan:

  1. Initial Phase (4-6 sessions): Target hair in the anagen phase every 4–6 weeks. This helps to treat the majority of hair follicles during their active growth phase.

  2. Maintenance Phase (every 4-6 weeks): As hair becomes finer and sparser, continue treatments to catch any hairs that may have entered the anagen phase later.

How to Optimize IPL Results for Long-Term Hair Removal

1. Use the Device Regularly

Consistency is key when using IPL for hair removal. Follow the recommended schedule to ensure you're targeting hairs in the anagen phase for maximum effectiveness.

2. Shave Before Each IPL Session

Shaving before each treatment ensures that the light energy is directed into the hair follicle, not the hair above the surface, which can burn and cause irritation. Always shave the area to be treated 24–48 hours before your IPL session.

3. Don’t Skip Maintenance Treatments

Once the initial treatment cycle is completed, it’s essential to schedule maintenance treatments to treat any hair that may have entered the anagen phase after your initial sessions. Maintenance sessions every 4–6 weeks will help you maintain smooth, hair-free skin for the long term.

4. Moisturize and Protect Your Skin

After IPL treatments, make sure to moisturize your skin and apply sunscreen regularly. IPL can leave the skin more sensitive, so it’s important to protect it from the sun to avoid hyperpigmentation and irritation.
