 How often should you be washing your hair?

   A-list celebrity hairdresser Jon Hala said: “You should only wash your hair when it’s absolutely necessary.”
   You’ll be able to tell whether your hair needs a wash or not by running your hands through it and if it still feels soft and bouncy, it’s likely it won’t need a wash.
   Mr Hala said: “Although the general recommendation is to wash it a maximum of one to two times a week, I’d say that it should only be washed when the hair is visibly oily.
   “If the scalp is itchy or there are signs of flakiness due to dirt, then it’s clear it’s time for a wash.
   “Remember, for a healthy scalp you need natural sebum for healthy follicles and washing your hair too regularly will reduce this.”

Cally Borg, hair expert and personal stylist for Amanda Holden told Express.co.uk: “You could look at doing an at-home remedy of an apple cider vinegar rinse, where you water down the vinegar at a 1:3 ratio and rinse your hair with it once a week.

Another hack is to add shampoo directly to your hair in the shower without the addition of water. Apply shampoo and run it through your hair for a few minutes to draw out the grease. Use cooler water to wash and cleanse.  

“Note, very hot water stimulates and excites the sebaceous glands creating more sebum (oil/grease) and remember, finish with conditioner working it only from midway down to the ends of your hair.”

What ingredients should I watch out for in products?
   When choosing hair products, however, there are some super ingredients - and ones you should absolutely avoid - according to Neal & Wolf founder and haircare specialist Neil Capstick.
He identified the great ingredients to include nourishing oils such as argan, jojoba, avocado, and sunflower seed, to all improve manageability, nourish dry ends and add incredible shine.
 Mr Capstick said: “Panthenol helps to lock in moisture, add shine and improve manageability, and shea butter can help moisturise while reducing frizz and flyaways.
   “Glycerin is also a natural humectant that helps to retain moisture in the hair.”
