In the initial weeks after a transplant, mild medical shampoos prescribed by the surgeon should be used to gently clean the scalp without disturbing grafts. Once the healing phase is complete, transplanted hairs behave like natural hair and do not require special products. They can be washed, styled, or treated normally. However, maintaining scalp hygiene and using nourishing products can improve overall hair health. With secure placement through DSHI, transplanted follicles remain strong. While no specific products are mandatory, a healthy scalp environment helps support long-term growth and maintains density naturally.
