Are you guilty of buying a new brand of shampoo every month, solely to prevent your hair from getting “used to” it? No need – hair isn’t a living thing, so there’s no way it can become immune to products and stop working. However, your tresses can look different in different environments (ie, cold weather, humidity, etc.), or if you have intense product buildup – and this can give the impression that your usual shampoo isn’t working anymore. To remove impurities and give your hair a fresh start, detox your locks regularly with the Damage Detox Purifying Shampoo.
