My hair is very fine but i have a lot of it.
I dont really have any issues with my hair other than i wash it everyday coz if i dont it gets greasy and thats a big no no.
I dont use any expensive fancy products on my hair, i simply use Alberto Balsam shampoo and conditioner, it runs at about a pound a bottle for each (1.57 US dollars) ive used these for years and would reccommend them.
Other than that the only other products i use are Pro Styling by Schwarzkopf before blow drying my hair for styling, or you can use it on dry hair for flat irons for straightening your hair which is what its meant for as its a heat protectant, this product smells great and makes your hair feel great too.
You can purchase this for around £ 1.20- 1.50
(1.88 - 2.35 US dollars)
My hair spray is called Silverkrin by Wella , i have used this for years as it has great hold but easily brushes out with no snagging so i love it.
I get the large tins 400 mls, 2 for £4.00 (6.26 US dollars) when they are on offer, but they normally run around £2.70 per tin. (4.23 US dollars)
