PRP for Hair in Tel Aviv: How It Works, Who It's For

Loss of density, diffuse shedding, early-stage balding: hair PRP is often presented as a miracle solution, which it is not. It is, however, a serious medical treatment that uses the body's own resources. Here is how it actually works, and who it makes sense for.

The principle: using the patient's own blood

PRP, for platelet-rich plasma, is an autologous method: the injected product comes entirely from your own blood. A standard blood draw is centrifuged, which separates the blood components and allows a plasma concentrated in platelets, rich in growth factors, to be isolated.

This plasma is then re-injected into the scalp, where these growth factors stimulate hair follicles that are in a resting phase, pushing them toward an active growth phase.

It is this autologous origin that explains the treatment's safety: there is no risk of rejection or systemic effect linked to a foreign substance, since it is your own cells. Find the full details on the site's PRP and exosomes for hair page.

What the concentrated platelets actually contain

Platelets don't just help blood clot: once activated, they release a set of proteins called growth factors, which play a role in tissue repair and regeneration. By strongly concentrating them through centrifugation and then re-injecting them at the follicle level, their local concentration is boosted well beyond what blood naturally contains, which enhances their stimulating effect on weakened follicles.

A method already used well beyond hair

PRP was not designed for hair: this technique has been used for longer in sports medicine and orthopaedics, to promote the healing of tendons or ligaments. Its use on hair follows the same biological principle, applied this time to the hair follicle rather than to joint tissue.

For which types of hair loss

PRP is not a universal solution for all hair loss. It is particularly indicated for:

• Androgenetic alopecia, the most common form of diffuse hair loss, linked to a genetic sensitivity to hormones.
• Early-stage balding, when weakened follicles are still present but produce finer hair.

It is, however, less suited to scarring alopecia or areas where follicles have completely disappeared: without a follicle to stimulate, there is nothing for PRP to act on.

Key takeaway: PRP stimulates weakened follicles, it does not create new ones. It is a treatment that is all the more effective when started early, before hair loss becomes too advanced.

How many sessions, and what results

A standard protocol includes 3 to 4 sessions, spaced 4 to 6 weeks apart, followed by maintenance sessions roughly every 6 months to sustain the benefit over time.

Results are not immediate: the hair cycle is slow, and it generally takes several weeks, or even a few months, to see a noticeable thickening.

Why the hair cycle imposes its own patience

Each hair follows a cycle with several phases, including an active growth phase and a resting phase that can last several months. PRP works by helping dormant follicles shift earlier into the active phase, but it cannot speed up the growth rate itself: it is this biological constraint, common to any serious hair treatment, that explains why results are judged over several months rather than after one or two sessions.

When to actually assess the results

The eye quickly gets used to its own reflection, which makes it hard to objectively judge a gradual change. This is why a comparison point, for example through photos taken under the same conditions before starting and then after several months of the protocol, gives a far more reliable picture than a day-to-day impression.

An honest treatment about its own limits

No serious medical treatment can promise a guaranteed result for hair regrowth: the response depends on age, genetics and the stage of hair loss at the time treatment begins. Most patients see a thickening of hair and a slowdown in hair loss, though not systematically or identically from one person to another.

It is this honesty about realistic expectations that sets serious medical care apart from the marketing promises sometimes found elsewhere, the same standard found for other treatments such as thread lifts.

What a session involves

Discomfort is generally low, although some areas of the scalp may be a little more sensitive. No social downtime is needed after the session: the blood draw, PRP preparation and injection all take place during the same appointment.

In short

• PRP uses your own blood, centrifuged to extract a plasma rich in growth factors.
• It is indicated for androgenetic alopecia and early-stage balding, not for areas without follicles.
• The protocol involves 3 to 4 sessions spaced 4 to 6 weeks apart, with maintenance every 6 months.
• Results are gradual and not guaranteed: they depend on age, genetics and the stage of hair loss.
