Hair filler is one of the hair loss injections used to support thinning hair. Despite the name, it does not add volume the way a facial filler does. The aim is to deliver active ingredients that nourish the hair roots directly into the scalp.

The formula used at our clinic combines biomimetic peptides, hyaluronic acid and vitamins. Biomimetic peptides are small protein fragments that mimic the body’s own signaling molecules. Together, these ingredients help support circulation and tissue renewal around the hair follicle.

• Hyaluronic acid: Hydrates the scalp and helps support the quality of the tissue around the root.
• Biomimetic peptides: Aim to support the activity of hair follicle cells and help protect them from external stress.
• Vitamins and minerals: Deliver nutrients the hair root needs to the area.

Because the formula goes straight into the layer where the hair roots sit, the active ingredients reach the target area. Unlike oral supplements, the effect is focused only on the treated scalp. Hair filler can be planned on its own or combined with other hair loss treatments.

Hair loss has many causes, and not every cause responds to the same treatment. That is why the type and cause of shedding are assessed at your consultation first. Hair filler is usually considered for:

• Thinning hair: Finer strands and a more visible scalp, in both women and men.
• Seasonal or stress-related shedding: Diffuse shedding that increases at certain times.
• Damage from coloring and styling: Dull, worn-looking hair after frequent coloring, heat and chemical treatments.
• Support after a hair transplant: People who want to nourish the scalp after a hair transplant.

Iron deficiency, thyroid problems or hormonal factors can lie behind hair loss, so blood tests may be requested and any underlying cause is treated separately. Hair filler supports that treatment; it does not replace it.

Round, clearly defined bald patches are a different picture. This may be alopecia areata, which needs its own assessment. Scalp itching, heavy dandruff or sores are also addressed first.

The treatment starts with an examination of your hair and scalp. The areas where shedding is most noticeable are identified and a personal plan is made.

Preparation is simple: wash your hair the day before and skip styling products such as gel or spray on the day. If you take medicines that can increase bleeding, such as aspirin, ask your doctor whether to pause them.

1. The scalp is cleaned with an antiseptic solution.
2. Hair is parted into sections to expose the scalp.
3. The formula is injected in small amounts into the affected areas with very fine needles.
4. The area is checked at the end; no dressing is needed.

The session usually takes 20–30 minutes, and you can return to your day straight afterward. Because the needles are very fine, most people tolerate the treatment well. Hair filler should be done by a doctor in sterile conditions. The same technique can deliver other formulas; for vitamin-based mixtures, see hair mesotherapy.

The protocol varies from person to person. At our Nişantaşı clinic, a course of 4 sessions is usually planned, one every 15 days over about 2 months. The exact number is decided at your consultation, based on how severe the shedding is and the condition of your scalp.

After the first course, occasional maintenance sessions may be recommended, timed according to how your hair responds. Hair filler can also be part of a wider plan:

• Growth factors from your own blood: It can be alternated with hair PRP / GRP.
• Care for the hair strands: It can be combined with hair botox for damaged lengths.

Recovery is short, but a few simple steps help the scalp settle and prevent irritation:

• Washing: Don’t wash your hair on the day of treatment; use a mild shampoo the next day.
• Heat and sweat: Avoid intense exercise, saunas, Turkish baths and pools for the first 24 hours.
• Chemical treatments: Wait a few days before coloring, perms or keratin treatments.
• Touching: Avoid rubbing the scalp or wearing a tight hat on the first day.

Mild redness, small bumps and scalp tenderness are common and usually fade quickly. Rarely, small bruises may appear at injection points. A balanced diet, good sleep and managing stress also support hair health during treatment.
