    Easy to use

    I can't say much about this product yet because I just started using it. So far, my hair fall does seem to be less than before.

    Just bought it. The problem is that I don't like washing hair everymorning. It is bad for my hair. I am not so confident it might work.

    Hey Suada,

    Thank you for sharing your feedback! We recommend to use this every night for at least 3 months. You do not need to wash your hair every morning if not desired! Please do reach out to the askINKEY team if you have any questions!

    Great, if you use regularly!

    I am still trying to make this a regular part of my hair care routine, but I usually apply this at night and wake up to hydrated and volumized hair.
