Here is a detailed guide to help those who have started losing their hair after their 20s. The following methods may be helpful if your hair loss period is within 5-6 years.

The overall approach can be summarized into two categories: internal and external treatments.

Internal treatments include:
*minoxidil, a topical solution that can be applied to the scalp daily; and
*non-potent ingredients, such as vitamins D and B, that can help promote hair growth.

External treatments include:
*minoxidil shampoo, which can be used twice daily; and
*finasteride, an oral medication that can help stop hair loss.

Other methods that can be used include:
*low-level laser therapy (LLLT); and
*hair transplantation.

In addition, it is important to maintain a healthy lifestyle, including a balanced diet, regular exercise, and reducing stress. Avoiding heat styling tools and using a gentle shampoo can also help promote hair growth.

It is important to note that results may vary depending on individual factors, and it may take several months to a year to see any significant improvements.
