Follicle injections are a treatment method that injects specific medications into the scalp to help relieve hair loss and promote hair growth.

This treatment is customized according to each person’s hair loss condition and cause,

and the number of sessions and treatment period can vary depending on the personalized treatment plan.

So, how many follicle injection treatments do most patients need to see results?

When Follicle Injection Results Begin

Most patients usually begin to notice changes in hair density and thickness after about 4 to 6 sessions.

However, this varies from person to person and can depend on the cause of hair loss, scalp condition, and the type of medication used.

For example, patients in the early stages of hair loss may see results with relatively few treatments, but untreated or advanced hair loss may require more sessions.

The Importance of Continuous Treatment

To maximize the effects of hair loss follicle injections, continuous treatment is important.

Most doctors recommend more than 10 treatments at 2-week intervals,

and emphasize that ongoing maintenance treatments are needed afterward to sustain the results.

Maintenance treatments are usually carried out at 1- to 3-month intervals and help stimulate new hair growth and maintain the health of existing hair.

Consistent care is necessary to help prevent hair loss from progressing.

Combined Treatments with Follicle Injections (5 Types)

Follicle injections can be more effective when performed together with other treatments than when used alone.

Typical combination treatments include the following.

  1. Oral medications: drugs such as finasteride or dutasteride

  2. Topical treatments: external products such as minoxidil

  3. Low-level laser therapy: stimulates hair growth by promoting blood flow to the scalp

  4. Hair nutrition supplements: intake of vitamins and minerals essential for hair health

  5. Personalized device-based treatment: customized device treatment based on the patient’s hair loss condition and treatment ingredients

Patient-Specific Treatment Plan

To maximize the effects of follicle injections, it is important to create a personalized treatment plan based on the patient’s scalp condition and the cause of hair loss.

To do this, before starting hair loss treatment, it is important to understand your current hair loss stage and its cause through a hair loss examination.

A hair loss examination evaluates the scalp condition, follicle health, physical condition, and more in a comprehensive way, helping to establish your own treatment direction.

After consulting with a specialist, deciding on the treatment interval and combination therapies that are appropriate for your condition can help you begin more effective hair loss management.

Conclusion

Hair loss follicle injections are an effective method for managing hair loss, and results can usually be felt after 4 to 6 sessions, but ongoing maintenance treatment is necessary.

Because the number of treatments and the interval needed can differ from patient to patient, it is important to establish a plan that suits you through consultation with a specialist.
