Hair loss is deeply personal. For some, it’s a slow process—thinning at the crown, a widening parting, or a receding hairline that inches back over time. For others, it happens suddenly—after childbirth, illness, or extreme stress. Whatever the cause, the impact goes beyond appearance. Losing hair can affect confidence, self-image, and even the way we interact with others.

The search for effective treatment is often exhausting. Hair transplants can be prohibitively expensive, costing anywhere from £3,000 to £15,000, depending on the clinic and the number of grafts required.

They’re also invasive, with a lengthy recovery period and no guarantee of success. Topical treatments and medications, such as minoxidil and finasteride, can work for some but require lifelong use and may come with side effects. Meanwhile, over-the-counter serums, supplements and hair treatment products rarely deliver meaningful, long-term results for hair loss conditions.

Keralase™, recently introduced in the UK, combines advanced laser technology with a powerful growth serum to stimulate natural hair regrowth. It’s a non-invasive, pain-free option that doesn’t rely on surgery or daily medication. Instead, it works by creating the optimal conditions for hair follicles to start growing again.

How does Keralase™ work?

Keralase™ was developed by Seriderm, a global leader in innovative medical and aesthetic laser technology. It is built on two key technologies:

1. LaseMD Non-Ablative Fractional Laser

This laser creates microscopic channels in the scalp, making it easier for the treatment serum to absorb. Unlike traditional ablative lasers, which can damage the skin and require downtime, this laser uses water—not heat—to create these microchannels. This means there’s no pain, no peeling, and no need for recovery time.

2. KeraFactor® Serum

After creating the microchannels, your practitioner will apply the KeraFactor® Serum. This highly concentrated formula delivers biomimetic polypeptides and growth factors that enhance scalp health and stimulate hair follicles to enter the active growth phase.

What makes this serum unique is its nanoliposome delivery system. The protective nanoliposome shell encases each growth factor, enabling it to penetrate deeply into the scalp and absorb five times more effectively than standard topical treatments.

Together, these two steps increase blood supply to the scalp and reawaken dormant hair follicles, leading to thicker, stronger, and healthier hair over time.

Who is Keralase™ for?

Keralase™ is suitable for both men and women experiencing hair loss due to a variety of factors, including:

• Androgenic alopecia (male and female pattern hair loss)

• Telogen effluvium, a temporary form of hair loss often triggered by childbirth, illness, or stress

• Thinning due to hormonal imbalances, such as thyroid disorders

• Age-related hair loss

• General hair thinning at the crown or frontal hairline

People that aren’t yet ready for a hair transplant but want a proven, clinically backed treatment to stimulate regrowth can also try this treatment.

What to expect from the treatment

Experts describe Keralase™ as a quick, comfortable, and effective treatment, with each session lasting 30 minutes. While a full course of five treatments, spaced about four weeks apart, is recommended for optimal results, you don’t necessarily need all five to see improvements.

Many people notice their hair becoming thicker—or even changing colour—shortly after the first session. From there, it’s up to you to decide if you’re satisfied with the results or wish to undergo more sessions.

Right after the treatment, patients are advised not to wash their hair for 24 hours to allow the serum to fully absorb. Other than that, there are no restrictions and no recovery time needed, so it is an easy treatment to fit into your schedule.

The process is meant to cause no pain or discomfort either, so there’s nothing to lose sleep over, even if it’s your first time undergoing this type of procedure.

You may see results straight away, but also a gradual improvement as you go through the sessions—noticeable changes typically appear within three to four months, with continued progress over time.

Here is an example of a patient eight weeks after the treatment (there are various other before-and-after photos online):

Cost and availability

Keralase™ is now available in two clinics across the UK: Feonix Aesthetics, in Coventry, and the Face and Body Clinic, in Harley Street, London. It costs £600 per session (a total of £3000 if you choose to undergo the recommended five session).

A new era in treating hair loss

Hair loss isn’t just about aesthetics—it can take a real toll on confidence and daily life, and unfortunately, it often worsens over time. That’s why it’s best to explore solutions early rather than ignoring the issue and letting it progress.

Of course, the key is finding a treatment that truly works for you. Many options are invasive, costly, or inconsistent in their results. If you’re open to trying something different, Keralase™ offers a non-surgical, scientifically backed approach designed for natural, long-term improvement.
