The frequency of washing hair that has fallen out can vary depending on the individual's hair type and lifestyle. Generally, it is recommended to wash hair that has fallen out every two to three days with a mild shampoo and conditioner. This will help remove dirt, oil, and product from the scalp and prevent the buildup of bacteria and fungus. It is important to use a gentle shampoo that is free of sulfates and parabens, as these can be too harsh for the delicate scalp.
It is also important to massage the scalp with a shampoo brush or fingertips while washing to stimulate the follicles and promote healthy hair growth. As the hair grows back, it is important to use a conditioner to keep the strands hydrated and healthy looking. Additionally, it is important to avoid over-washing, as this can strip the hair of its natural oils and cause irritation to the scalp.
Overall, the frequency of washing hair that has fallen out should be determined based on individual hair type and lifestyle, as well as the amount of product used. For those with dry or damaged hair, washing every two to three days may be sufficient. Those with oily hair may need to wash more frequently. Additionally, those who use styling products should wash their hair more often to prevent product buildup.
