I have super-thin, fine hair that becomes flat and oily throughout the day. The one way I've combated this problem through the years is by using volumising shampoos that give my locks some added bounce. A few months ago, I was recommended to try this Sachajuan Thickening Shampoo ($43), and it is hands down my favourite new product.
In case you're not familiar with the Swedish line, it's carried at department stores and at Sephora. The brand is driven to create simple and clean beauty products that give your hair exactly what you need without extra harmful ingredients.
The name does exactly what it says: it makes my hair feel thicker and silky soft. It's formulated with a blend of sea algae, which helps nourish and repair your tresses while adding a touch of softness and volume. I use it in combination with the moisturising Sachajuan Thickening Conditioner ($41), which detangles my hair with ease. Both of the products contain UV and heat protectants to help keep your hair healthy. If you think you could use a boost, you'll want to give these a try.
Sachajuan is not only for thin hair; the brand carries a wide array of products for everything from curly locks to dyed tresses. Make sure to check out everything and see what suits your needs.
