LaseMD Keralase for Hair: How It Works and Who It’s For

LaseMD Keralase for Hair is a two part scalp treatment that pairs a gentle laser with a serum rich in growth factors to support thinning hair. It suits people in the early stages of shedding or thinning who want a clinical option without needles or surgery.

Hair loss rarely happens overnight. Most people notice a wider parting, a thinner ponytail or more hair in the shower drain months before anyone else does. By then, many have already tried shampoos, supplements and oils with little change. That is usually the point where a clinic treatment starts to make sense.

In this guide we explain what the treatment involves, how it works on the scalp, what sessions feel like and, most importantly, who is likely to benefit and who should look at something else first.

What Is LaseMD Keralase?

LaseMD is a low energy laser made by Lutronic. It uses a thulium wavelength of 1927 nanometres, which works on the surface layers of the skin without breaking it open. It was first developed for facial skin renewal, but it has become popular on the scalp because it helps the skin absorb topical products far more effectively.

Keralase is the name given to the combination of that laser with KeraFactor, a serum made for the scalp. The serum contains growth factors and peptides that support the environment around each hair follicle.

On its own, a serum applied to the scalp only gets so far. The outer layer of skin is a barrier, and that is its job. LaseMD temporarily opens tiny channels in that barrier so the serum can reach where it is needed. That pairing is the whole idea behind the treatment.

How LaseMD Keralase Works

The treatment works in stages: the laser creates microscopic channels in the scalp, the growth factor serum goes on straight away, and the follicles get a better environment to return to active growth.

1. Scalp preparation. Your practitioner cleans the scalp and parts the hair into sections so the laser can reach the skin. There is no need to shave your head.
2. Laser pass. The LaseMD handpiece glides across the thinning areas. It delivers controlled heat into the upper layers of the scalp, creating thousands of tiny treatment zones while the surrounding skin stays intact.
3. Serum application. KeraFactor is massaged into the treated areas while those channels are still open. This is the window when absorption is highest.
4. Aftercare. You leave the serum on the scalp, usually until the next day, before washing your hair.

Why does this help? Hair grows in cycles. When hair is thinning, more follicles sit in the resting phase, and the hairs that do grow become finer with each cycle. Growth factors are signalling proteins that support cell activity around the follicle. Delivering them directly into the scalp aims to encourage more follicles back into the growth phase and help strands come through thicker.

The gentle heat from the laser may also encourage circulation and renewal in the scalp itself, which supports overall scalp health.

What a Session Feels Like and How Many You Need

Most people describe the laser as a warm, prickly sensation, and a session usually takes around 30 to 45 minutes. Numbing cream is rarely needed on the scalp, though your practitioner can advise if you are sensitive.

Afterwards the scalp may look slightly pink and feel warm, a little like mild sunburn. This usually settles within a day or two. There is no open wound, and most people go straight back to work or their normal routine.

A typical course is around six sessions spaced two to four weeks apart, although the right plan depends on how advanced your thinning is. Many people notice less shedding first, then better density and thicker strands over the following months. Hair grows slowly, so results are best judged three to six months after you start. Maintenance sessions every few months can help keep results going.

Who LaseMD Keralase Is For

LaseMD Keralase works best for people with early to moderate thinning whose follicles are still active, rather than areas that have been completely bald for years.

You may be a good candidate if you:

• have a widening parting or general thinning across the crown
• are noticing more shedding after stress, illness or pregnancy
• have early pattern hair loss, whether you are a man or a woman
• want a treatment with no needles and very little downtime
• already use medical treatment and want something to support it

It suits both men and women. Women often choose it because diffuse thinning is so common for them, and many prefer a drug free approach.

Who should wait or choose something else

The treatment is not right for everyone. It is usually not recommended if you:

• are pregnant or breastfeeding
• have an active scalp infection, open wounds, or a flare of psoriasis or eczema on the scalp
• have scarring alopecia, which needs a dermatologist’s diagnosis first
• have smooth, completely bald areas where follicles are no longer present
• are prone to keloid scarring or take medication that makes your skin sensitive to light

Sudden or patchy hair loss also deserves a medical check first. Thyroid problems, low iron and hormonal changes can all cause thinning, and treating the cause matters more than any scalp treatment.

How It Compares With Other Scalp Treatments

LaseMD Keralase sits between gentle scalp care and more intensive regenerative treatments, and a consultation helps decide which one fits your stage of hair loss.

If your main concern is a dull, congested or flaky scalp with mild thinning, HydraFacial Keravive Hair and Scalp may be a softer place to start. It cleanses and exfoliates the scalp, delivers nourishing peptides and comes with a take home spray to use between sessions.

If thinning is more established, Exosome Hair Rejuvenation uses exosomes, tiny messengers that carry signals between cells, to support follicle repair. People often choose it when they want a more intensive regenerative approach.

Some people combine treatments over time, for example starting with scalp health and then moving on to a course of Keralase. A practitioner can map this out once they have looked at your scalp and history.

Is LaseMD Keralase Right for You?

LaseMD Keralase is a sensible choice if you are seeing early thinning, want to act before it progresses and prefer a treatment with no needles and minimal downtime. It works best when started early, completed as a full course and paired with good scalp care at home.

The most useful first step is an honest assessment. At Cavendish Clinic, every hair treatment begins with a consultation to examine your scalp, talk through your history and recommend the option that suits your stage of hair loss, even if that turns out to be a different treatment.

Frequently Asked Questions

Does LaseMD Keralase hurt?

Most people feel warmth and a light prickling during the laser pass. It is generally well tolerated, and the session is short.

How soon will I see results?

Less shedding is often the first change, usually after a few sessions. Visible improvement in density is best judged three to six months after you start, because hair grows slowly.

Is there any downtime?

Very little. The scalp may be pink and warm for a day or two. Avoid washing your hair until the following day so the serum has time to work.

Can I colour or style my hair after treatment?

Avoid colouring, heat styling and harsh products for a few days. Your practitioner will give you a full aftercare plan.

Are the results permanent?

Keralase supports the follicles you have, but it cannot stop genetic hair loss from continuing. Occasional maintenance sessions help keep your results going.

Can I combine it with other hair loss treatments?

In many cases, yes. It is often used alongside medical treatments or other scalp therapies. Tell your practitioner about everything you currently use.

Is LaseMD Keralase suitable for women?

Yes. It is popular with women who have diffuse thinning, including thinning after pregnancy once breastfeeding has finished.
