I’ve been using the Oligo Blacklight Smart Developer 10 Volume for a few weeks now, and I’m really impressed. It’s gentle on my hair but still gives great lift and color development. The gradual bond protection technology seems to make a noticeable difference—my hair feels stronger and less damaged after each use. Plus, the 1-liter size is perfect for multiple applications without running out quickly. Definitely a great product for anyone looking for a reliable developer that also cares for hair health!

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 helps maintain strength during coloring, which is great. However, the scent is a bit strong for my liking, and the large bottle can be tricky to store. Overall, it’s a solid product that works well but could improve on fragrance and packaging.
