Nowadays, more and more hair salon operators are focusing their service items on scalp care and maintenance, especially dealing with the problem of hair loss. This study is mainly to explore the findings of androgenetic alopecia and take the patients with typical male baldness as the case study, and conduct case improvement analysis and discussion. Therefore, this study integrates the principles of hair growth and the causes of androgenetic alopecia, and proposes a side-effect-free scalp care and hair growth process for androgenetic alopecia patients. Research results show that this treatment process can allow the pores of the hair transplant to open normally, so as to extend the life cycle of the hair and increase the chance of creating new hair. However, comparing the visual effects before and after the experiment on the hair on the top of the head, although the visual effect is slightly improved, the hair volume has not yet reached the level sufficient to cover the scalp.
