Over the last year my hair has completely stopped growing. I used to have very long hair and got it trimmed regularly. I have had to stop trimming it as it is now only barely to my shoulders. I am afraid to cut any more of it because the length won't grow back. I am female and always had long hair, this is a major worry for me. It is not unusual to see this sort of problem in someone who has used long-term chemical treatments on their hair. This may cause chemical alopecia (hair loss), or a telogen effluvium, with shedding and growth retardation. Obviously, the best course of action is to cease using the products, or to find an alternative. A consultation with a dermatologist, or a good hair loss/hair restoration physician is in order, so that a definitive diagnosis may be made. Laboratory studies and/or a scalp biopsy might be needed to reveal the true cause and nature of the condition. We always recommend using the haircycle products as they help to accelerate anagen. Haircycle products are extraordinarily effective and highly potent blend of DHT inhibitors, antioxidants, anti-inflammatory, cell proliferates, anagen stimulators, nitric oxide , precursors and androgen blockers.
