Cutting your hair regularly actually prevents your hair from splitting on the ends, so this is what creates the illusion that your hair is growing faster. The hair is much more healthy overall. No split ends means no breakage which means longer-looking hair.
So while cutting your hair might not make it grow faster, it’ll keep it looking healthy. By leaving your hair for too long between trims, it becomes prone to breakage and splitting. If this occurs, when you eventually get around to having it cut, you’ll have to chop it higher than previously desired. In this way, regular trims can help you to maintain longer hair but it won’t promote growth.
So, how often should you get it trimmed?
On average, hair grows around 5-6 inches per year, which is about 1/2 inch each month.
If you have long hair and want to keep it long, I’d recommend [getting a trim] every 8-10 weeks unless your hair is extremely fragile, then every 8 weeks you should keep it healthy and help build strength. If your hair is cut in a shorter style and you want to keep it looking sharp, you’d need it trimmed every 6 weeks.
And what actually helps hair to grow?
It’s all about the condition you keep it in. Getting regular trims or ‘dusts’ and choosing quality products is vital. She suggests using shampoos, conditioners and styling products that are free from SLS, Silicons and Parabens to nourish your hair and manage its PH balance. In turn, this keeps the hair shaft smooth, full of elasticity and supple.
Lastly, diet goes a long way in keeping hair growth on the right track. Avocado oil, coconut oil and fish oil all contribute to shiny, healthy hair and skin, as do nuts and plenty of fresh fruit and vegetables. Make sure you get enough sleep and use silk pillow cases to keep hair smooth and glossy and prevent unnecessary breakage.”
