Most people notice increased hair shedding around two to four months after significant weight loss begins. This is because hair follicles respond to changes in the body with a delay, meaning shedding often occurs weeks or months after the initial trigger.

In most cases, no. Hair shedding following rapid weight loss is usually temporary, and normal hair growth resumes once the body has adjusted and the hair growth cycle returns to normal. Supporting your scalp and hair throughout this period may help encourage healthier regrowth.

The Megi Scalp Activation Derma Roller and Growth Stimulating Hair Serum are designed to work together to create the ideal environment for healthier hair growth. The derma roller gently stimulates the scalp, while the serum delivers clinically backed ingredients directly to the hair follicles. Used consistently as part of your routine, they can help support stronger, fuller-looking hair during periods of temporary shedding associated with rapid weight loss.

Hair growth takes time. While shedding may begin to slow sooner, noticeable improvements in hair thickness and density typically take around 90 days or more. Consistency is key, as healthy hair grows in cycles rather than overnight.
