GHD Shop offers you the most durable hair quality. Our hair extensions can last a very long time, depending on how you maintain it. Therefore, we recommend that you wash and treat your hair extensions like your own hair. Raw hair is unprocessed human hair from a single donor that has not undergone any chemical processing. The only process it goes through is sanitization. It is also the most natural and original form of hair available and as such it can last for years with proper hair care. Virgin hair is also top quality. The rule of thumb is at least 2-4 years.
