Which lasts longer: hair smoothening or hair straightening?
Thank you for clarifying that. Can hair smoothening be done at home or does it require professional help?
It is recommended to get hair smoothening done by a professional hair stylist as it involves using chemicals which can be harmful if not used properly. However, there are some at-home hair smoothening kits available but it is important to follow the instructions carefully.
