Yes, you can absolutely recolor your hair if you don't like it! There are many different methods out there to help you do this. The most popular way is to use a box dye from the store which will allow you to choose from different shades of color. However, for people who want a more professional look or have never dyed their hair before, going to a salon may be the best option. A stylist can work with you on achieving the exact shade that you're looking for and they'll also provide advice on how to maintain it afterwards. If neither of these options appeals to you, then there's always the possibility of using temporary dyes such as chalks or sprays that wash out over time without doing too much damage. Whichever route you decide on, make sure that anything used is suitable for your type and condition of hair so as not to cause further damage.
