I have used solar oil for a long time. It helped, but my nails still couldn’t grow past a certain point without splitting or breaking. I purchased this cuticle oil 3 weeks ago and my nails have grown longer!! No splitting, no breaking and I use my hands all day every day.. the bottle is huge! It will definitely last me a long time even though I apply several times a day. The scent is just ok.. it is mild and not overpowering. I took this picture after cleaning up my kitchen this morning. No oil has been applied since last night, so my nails might look a little drier than normal.
