We spend a grip on hair extensions, so we might as well get our money’s worth by grooming them properly to ensure longevity. The rule of thumb is to treat weaves as if they were your own hair, which means with lots of TLC. And while these strands aren’t growing out of your scalp, you bought it (with receipts to prove it), so technically it is “your hair” and should be treated as such. Extensions are an investment with a lengthy pay off. They can last for weeks on end if maintained correctly with these products and pro-tips.
