I personally Can’t live without My Dry shampoo at festivals and now Inecto have released I am over the moon. The inecto Range is VERY reasonably priced with nearly everything in the range around the £2 mark. The Dry shampoo is only £2.99 with a light fragrance of coconut it is perfect for camping, taking to festivals or just to use if your hair starts getting greasy in the heat.
Remember you can not take aerosols in hand luggage but this would be perfect to use to spruce up your locks if you have a full day excursion whilst on your holiday!
For £2.99 From Mistrys its at least worth a try!
