Hair Loss Treatment: A Guide to PRP, Mesotherapy, and Hair Transplantation

Hair loss is a complex process that is not attributable to a single cause and can follow a different course in each individual. For this reason, hair loss treatment is not based on a single method applied the same way to everyone; instead, a personalized approach is developed taking into account the cause, stage, age, and overall health of the individual. Although PRP, hair mesotherapy, and hair transplantation are among the most commonly used options today, only a physician, after an examination, can decide which one — or which combination — is appropriate.

The Main Causes of Hair Loss

Many different mechanisms can lie behind hair loss. The most common type is androgenetic hair loss linked to genetic predisposition, which follows a progressive course over time. In addition, a temporary but intense type of shedding known as telogen effluvium — seen after stress, the postpartum period, sudden weight changes, or serious illness — is also a frequently encountered condition. Iron deficiency, thyroid function disorders, deficiencies in B12 and zinc, side effects of certain medications, and infections affecting the scalp can also contribute to hair loss. Treatments applied without first determining the type and cause of the hair loss may not produce the expected result; for this reason, the first step should always be an accurate assessment.

In the process of determining the cause of hair loss, the physician may resort to additional assessment methods such as dermoscopic examination, blood tests, or a trichogram, in addition to a scalp examination, where necessary. These examinations help distinguish whether the hair loss is androgenetic or due to a temporary cause, and allow the treatment plan to be shaped accordingly. A treatment started without an accurate diagnosis can lead to both wasted time and unnecessary cost.

What Is PRP Treatment, and How Is It Applied?

PRP (Platelet Rich Plasma) is a method based on injecting the scalp with plasma obtained from the person's own blood that has been enriched with platelets. The growth factors found in platelets are thought to support blood flow and cellular activity around the follicles. PRP is generally applied in sessions repeated at certain intervals and can be used either alone or together with other treatments. The effectiveness of PRP can vary from person to person and may not produce the same result in all types of hair loss; for this reason, it is important to discuss expectations realistically with a physician before starting PRP.

PRP is typically performed in a clinical setting: blood is drawn, processed through a special procedure, and then injected into the scalp using fine needles. Temporary symptoms such as mild redness or sensitivity may occur after the procedure. The frequency and total number of sessions are determined by the physician according to the person's condition; some patients may also be advised to have maintenance sessions at certain intervals.

Hair Mesotherapy and Its Effects

Hair mesotherapy involves applying vitamins, minerals, amino acids, and various active ingredients that support scalp health directly to the scalp using fine needles. The purpose of this method is to deliver the nutrients the follicles need directly to the target area and to support scalp microcirculation. Mesotherapy is usually applied as part of a session program and may be chosen for mild to moderate thinning, or as a complement to other treatments. The content and frequency of mesotherapy sessions should be determined by the physician according to the person's scalp condition and any deficiencies; a standard protocol should not be applied identically to every patient.

Unlike PRP, mesotherapy does not use the person's own blood but rather pre-prepared mixtures containing vitamins and nutrients. Some physicians may plan PRP and mesotherapy together in separate sessions so that they complement each other. Which content and frequency are appropriate should be assessed based on the person's scalp analysis and any deficiencies present.

When Does Hair Transplantation Become Relevant?

While treatments such as PRP and mesotherapy aim to support the function of existing follicles, hair transplantation is a permanent solution considered for areas that have permanently closed or largely lost their follicular activity. Hair transplantation generally becomes relevant when hair loss has concentrated in a specific area and reached a point where it can no longer be stopped or slowed with medical treatments. Before deciding on a hair transplant, it is important to assess whether the hair loss is still active; in the case of an active, rapidly progressing hair loss process, planning medical treatments before or alongside the transplant is often recommended to support the long-term result.

It should be kept in mind that the supply of hair in the donor area is limited for people planning a hair transplant; for this reason, medical support aimed at preserving the existing natural hair is generally continued even after the transplant. This aims to keep both the transplanted and the existing follicles healthy for a longer period.

Expert Support in Choosing the Right Treatment

The most important step in hair loss treatment is a personalized diagnostic and planning process. Two people presenting with the same complaint may be experiencing hair loss for entirely different reasons; for this reason, rather than choosing a treatment on your own based on general information found online, the healthiest approach is to have an evaluation supported by a scalp examination and, if necessary, blood tests. Rather than being alternatives to one another, PRP, mesotherapy, and hair transplantation can be viewed as complementary options addressing different needs; in some cases, these methods can be planned together. Since results can vary from person to person, it would not be accurate to guarantee a specific degree of improvement or density.

In cases of sudden-onset, irregular, localized hair loss accompanied by additional symptoms such as itching, redness, or flaking, an underlying skin condition or systemic issue may be involved; in such cases, rather than hair transplantation or cosmetic treatments, it is necessary to first consult a physician and obtain an accurate diagnosis. Everyone experiencing hair loss is advised to consult a physician to create a treatment plan suited to them and to take part in a regular follow-up process.
