The duration of AGA (male pattern baldness) treatment varies depending on the treatment used and the progress of the individual's thinning hair, but long-term care is required; since AGA is a progressive alopecia and is not cured completely, it is important to continue treatment. Below is an outline of the approximate time until results are achieved for each typical treatment method and the time frame for continuing treatment.
1. Finasteride (Propecia) and dutasteride
- Time to Effectiveness: It is common for finasteride and dutasteride to inhibit the progression of hair loss and hair growth to be felt after 3 to 6 months of use. However, there are individual differences, and some people experience effects only after about one year of use.
- Duration of treatment: These medications are effective only for as long as they are used, and when they are stopped, the hair loss will progress again. Therefore, long-term use is recommended.
2. Minoxidil (topical application)
- Time to Effect: Minoxidil often begins to show effects 4-6 months after use. During the first few months, hair may temporarily fall out (initial hair loss) as the hair growth cycle is regulated, but hair will grow back as treatment is continued.
- Duration of treatment: Minoxidil also requires continuous use. Long-term use is recommended, as discontinuation of use will result in regrowth of hair loss.
3. Mesotherapy (hair growth injection)
- Time to Effectiveness: Mesotherapy is a treatment method in which ingredients and growth factors effective for hair growth are injected directly into the scalp. It is estimated to take two to three months to show results, but this depends on the frequency of treatment and the individual’s constitution.
- Duration of treatment: Monthly treatments are common for the first few months, followed by maintenance treatments every two to three months.
4. Low power laser therapy (LLLT)
- Time to Effectiveness: LLLT typically takes 3-6 months to show results.Treatment should be continued on a regular basis to maximize the effectiveness of the treatment.
- Duration of treatment: It is recommended that treatment in the clinic or at home with a laser cap be done several times a week and continued as maintenance after the effects are realized.
5. Hair transplantation
- Time to effect: In hair transplant surgery, the transplanted hair gradually begins to grow back 3-6 months after surgery, and the final effect appears in about 12 months.
- Duration of treatment: Once hair transplant surgery is performed, the transplanted hair will continue to grow naturally. However, hair in the untransplanted area may continue to be affected by AGA, so continued use of finasteride and minoxidil is recommended after surgery.
6. Other treatments (e.g., lifestyle modification)
In addition to drug treatment, lifestyle modification is also important in AGA treatment. Efforts to maintain hair health, such as proper nutrition, adequate sleep, and stress management, should be continued over time in parallel with treatment.
Summary
The length of time it takes for AGA treatment to be effective depends on the treatment method, but generally 3-6 months is the standard. In addition, since AGA is a progressive alopecia, long-term treatment and care are necessary, as hair loss is likely to progress again if treatment is not continued.
