  • Can be a little heavy for fine hair

I just tried the amika Blockade Heat Defense serum and I felt like my hair was more hydrated and bouncy than normal. The serum has a very light texture, but it coats the hair really well and leaves an amazing shine to the hair.

The serum is also very lightweight and not sticky or greasy at all on the hair. The scent is really unique and can be a tester's preference. It is also paraben-free and sustainably certified by amika.

It is important to note that the texture is quite light, which is where the lightweight claim could be a little misleading. Also, if you've had a lot of build up or product in your hair already, this may not help.

That being said, the serum definitely worked well for me, especially with the help of a one-minute heat defense shampoo from amika.
