What kind of hair product should I use?

Well my hair is fairly straight except it kind of curls out on the end of my hair but I'm not sure whether to buy volume enhancing hair products, products that makes hair shinier, smoothing products(but my hair is pretty smooth). Sigh, picking hair products is hard. Btw, should I buy any hairsprays or other products like to straighten, smooth or get more volume?What kind of hair product should I use?
Avoid brushing wet hair. This will cause the hair to stretch and break. Use a wide tooth comb instead of a brush.





Trim your hair once every 6-7 weeks to avoid split ends.





If your hair is oily cut down on fried foods and fat. Drink plenty of water.





Shampoo your hair only when it鈥檚 dirty, washing everyday makes hair dry and hard to work with.





Always ask your stylist which colours compliment your style and skin tone.





Avoid over-the-counter haircare products, always buy professional ones from a salon.





When using straightners always use a protective spray to avoid damage to your hair.





Try to book your next appointment while you are in the salon that way you won鈥檛 forget when your hair needs a trim
