I’ve been using the Oligo Blacklight Smart Developer for a few weeks and really like how gentle it is on my hair, thanks to the gradual bond protection technology. It gives consistent results without too much damage. My only issue is that the scent is a bit strong, which can be off-putting during application. Overall, it’s a solid product that works well for at-home coloring.
