Customers with hair loss caused by autoimmune conditions, stress, or internal conditions
Hi! A lot of our customers have had success with autoimmune conditions (alopecia, hypo/hyperthyroidism, lupus, cancer, and many more) which is considered an internal issue, meaning the hair loss was not caused from external damage. However, because autoimmune conditions are internal issues affecting your hormones and hair growth, we cannot prevent the hair loss, we can only help start new hair growth. We don't guarantee results, because everyone is different, but we do advise that if you'd like to try, try the smaller size in a small area to see how it works for a few weeks. If there is growth, then it is possible to grow the rest of your hair. I hope this helps! Thanks for inquiring!! Please let us know if you have more questions.
