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.

I’ve been using the Oligo Blacklight Smart Developer for a few months now, and I’m really impressed with the gradual bond protection technology. It’s gentle on my hair and helps maintain its strength even after multiple color treatments. The 10 volume strength is perfect for subtle lightening without damage. Plus, the large 33.8-ounce size lasts a long time, making it great value for the price. Highly recommend for anyone looking to protect their hair during coloring!
