I used to think there should be a special award for people who managed to finish a bottle of shampoo at the same time as their conditioner. But it turns out, there is actually a very good reason why your conditioner has so much longevity – you’re probably using the wrong amount of shampoo on your hair when you wash it.
It’s because you’re only meant to be using half the amount of conditioner as you do your shampoo. In fact, a lot of products that you use could be putting an unnecessary dent in your wallet, simply because you’re using too much.
For short hair you should only be using a dollop of shampoo about the size of a five cent coin. Yep, really. For average length hair (hair that falls somewhere between the chin and the shoulders lob lovers) use an amount about the size of a ten cent piece. If you have Rapunzel-like long hair, dish up some shampoo about the size of a 20 cent coin.
Turns out that drenching the hair in conditioner can actually lead to flat, lifeless hair that's weighed down. Here's our new hair mantra: My hand is not a conditioner cup.
Follow the general formula of a dollar-sized amount for medium length hair (slightly less for short hair and a tiny bit more for long hair).
