I use hair masks maybe once a week as I have long, thick hair prone to tangling. I use Amika products on my hair and like the range. The mask does a good job and is good value for money. I use it already.
The only issue I have with the sample I got in my September box is the size. Ridiculously small, and not enough for anyone with hair longer than closely cropped styles to use. Certainly not enough for me to use - wouldn't even cover half my hair. Most of the samples in my box this month were microscopically small, and not big enough to try the product properly. That was very disappointing - I did not feel like I got very good value for money at all.
