Hair loss is most often caused by the presence of DHT on hair follicle which can cause hairs to become weak and fall out. This is a natural process that most commonly occurs in men as they age but can affect men and women. Our home hair loss products protect against hair loss and support hair regrowth in a variety of ways which you can learn about more when shopping for each product. For comprehensive hair loss treatment, we would recommend using a hair supplement (Viviscal Professional), a growth shampoo (Watermans Grow ME), a derma roller (ZGTS Derma Roller) and an accelerator serum (Hairmax Accelr8). Using these products in conjunction is likely to result in the highest rate of success.
