Why does hair grow back after IPL laser hair removal machine treatment

Pulished on Feb. 14, 2022

IPL laser hair removal machine uses a concentrated beam of light (laser) to remove unwanted hair. The laser targets the pigment in each hair and damages it so that it can no longer grow. At first, it will look like the hair has been removed, but if you don't follow the aftercare instructions, some of the hairs can grow back.

Many IPL hair removal machine suppliers have reported that some fine hairs grow back after the first few sessions in some treated areas. This is completely normal as it means that any remaining follicles which have been missed by your initial treatments are being regrown.

It's important to note that these hairs are more transparent and finer than your original hairs. This means that they will typically be less noticeable than your pre-treatment hair, making it easier for you to maintain smooth, silky skin with less effort.

Your hair grows in cycles and not all will be at the same stage when treatment is given. Hair follicles that are still in their growth phase will have pigment in them, so they'll absorb the energy from the laser and respond accordingly. Follicles that are dormant will not grow back as long as they remain dormant. The problem is that many hair follicles are naturally resistant to professional IPL machines and remain in their growth phase even after treatment.

The exact rate of regrowth varies from person to person, but generally most patients see about a 30% reduction in hair follicles. This means that about 70% of treated hair follicles are still present, but in their dormant phase after initial treatment. If you do nothing further, these hairs will eventually return to their growth phase and begin sprouting new hairs within a few weeks or months. So what can you do to avoid that? Keep reading to find out!

Why does hair grow back after IPL laser hair removal machine treatment

What is the IPL machine?

IPL laser hair removal machine is the cutting-edge technology that uses intense pulses of light to destroy collagen and stop hair growth. 

The light from the professional IPL machine is absorbed by pigmented areas in the skin, such as hair follicles or brown spots, and converted into heat energy. The heat energy then destroys the targeted cells without damaging any surrounding tissue. It also stimulates collagen production, which results in firmer skin.

Unlike lasers which use only one wavelength of light, IPL is a broad spectrum of pulsating light that is able to treat large areas simultaneously with speed and accuracy. In addition, IPL can treat more than one condition at once such as hair removal and wrinkle reduction or broken capillaries and redness!

Hair removal with an IPL laser hair removal machine can take anywhere from 10 up to 14 sessions. The number of maintenance sessions you require depends on how frequently your hair grows.

Hair removal with an IPL machine is permanent and there is maintenance needed to ensure your hair stays fine, soft and slow growing. But compared to waxing and shaving, it still is THE BEST hair removal method. With technology advancing and professional IPL machines becoming more accessible, it is also becoming cheaper than waxing. To keep hair from growing back too quickly, you should get touch-up treatments every six months or so.

Do hairs grow back even after IPL machine treatment?

This is the most common question IPL hair removal machine suppliers get from clients. And it’s an understandable one. After all, if you’ve spent your hard earned money on professional IPL machine treatments, the last thing you want is for hair to start growing back.

But we can assure you that there’s no need to panic just yet. There are a few reasons why hair may start growing back after your IPL sessions. Here are some of the common ones:

Your hair growth cycle:

If you're starting to see regrowth after your IPL sessions, it could be because some of your hair follicles were in their resting phase at the time of the treatment. It is possible that a small number of hair follicles missed their chance at being zapped by the laser during your treatment. These follicles eventually enter their active phase and you will notice new hair growth.

Emotional changes like stress or childbirth, as well as a major change in lifestyle can cause hair that was previously soft and downy to become thick, dark and strong. If you’re pregnant, going through menopause, or experiencing extreme stress, your body might begin to grow hair in places where it hasn’t before. Hormone changes or stress can trigger the onset of terminal hair growth.

Inconsistency in appointments:

When starting with an IPL laser hair removal machine, it is important to receive treatments no more than four weeks apart for at least 10 sessions. This will make sure you get the best results possible. The reason being is that each time you come in for a session, 25% of your hair is reduced. Hair that has not yet been treated grows back much slower and finer. But if treatments are spaced out too far or too few sessions are done, hair growth will return.

Once you’ve had your initial course of treatment, it’s highly likely that there are still a few follicles left in your skin that haven’t been treated. And if you don’t have follow-up treatments, these follicles will start producing new hairs.

That’s why it is important to have regular top ups after your initial course of IPL treatment. Typically this can be once a month or once every two months, depending on how quickly your hairs grow. But these top up treatments will help to keep any new hair growth at bay so that you can maintain your smooth, hair-free skin for longer.

If you have been following our advice and having regular top up sessions, then there is nothing to worry about. Even if the hair grows back, they will be minimal and unnoticeable.
