Goldwell Men Reshade Shots 4x20ml - 5CA light ash brown

Hair colouring is still a no-go for many men. Often, men experience a helmet effect after colouring, which appears unnatural. This discourages many from taking this step as their hair gradually grays. Goldwell Men Reshade Shots are the gentle alternative to colouring for men. This hair product for men provides a consistently natural grey reduction without helmet effect and without regrowth lines! The Reshade Shots ensure a subtly refreshed and younger appearance without a dyed look. The result is very natural and fades over time, rather than growing out at the roots. Additionally, the hair appears visibly fuller and looks entirely natural with reduced grey proportions. The application time is only 5 minutes, and it is completely straightforward. The Reshade Shots are available in the following shades, covering a wide range of grey tones: light ash brown dark ash blonde light ash blonde medium ash brown The Shots wash out evenly and consistently, preventing unnatural colours and always delivering a natural result. Goldwell offers with the Men Reshade Shots a very natural method for grey hair coverage for men without appearing coloured.
