This post is just some quick information I found useful when trying to darken synthetic hair.
As you all know, it is impossible to dye synthetic hair because the fiber they use does not absorb the dye. I have seen some youtube tutorials where they tell you to use fabric dye such as rite or speedball paint. Both methods are messy. Another reason the speedball paint method is bad is because you have to mix it with alcohol, it smells and just a headache.
The two products I used below helped me darken sythetic hair that was too blonde to a more brown, honey blonde color that would fit my brown skin.
Streaks N Tips > This is a brown spray that tints the hair brown and it really works well.
Fanci Full in Plush Brown> This is a liquid that you apply to the dry hair. When you apply it at first it is dark but when it dries it is not as dark as when it is wet so you have to reapply until you get the desired color you want.
