Ok! So I actually bought this (Calcium Boost) and the Protein Boost. My nails were in bad shape after placing press-on nails. They were peeling, chipping and once I got them to an “ok” length they would one by one start developing a crack on the side and it would go downhill from there causing me to cut them short and start from scratch again. I have been using the Calcium Boost for exactly 6 days now and my nails are growing steadily. I dont feel them thicker or stronger though. However, I think by now I would have started to see some thin cracks at least and nothing so far. I have one more day left of this and then I’ll try the Protein Boost and leave a review on there as well. I also do want to state that I have used Orlys Nail
Defense every day before using the new boosts and at first it was working great but Im not sure if so much use has caused my nails to just not like it much because my nails were still breaking. All in all, this Calcium boost seems to be doing its claim of “nourishing dry, damaged, and thin nails” and Im excited to see my nail journey!
