Luxlorah Nail Growth Oil (Cuticle Oil)  Nourishes the nails and makes them Stronger, Longer & Shinier within 2 to 6 weeks time, depending upon whats the issue is. 

If you just have slow growth then it would take only 2 to 3 weeks to start noticing the results

If your nails are weak and they break easily. Then it would take 4 to 6 weeks because in this case nails will have to get stronger from roots and once they grow longer they wont be break so easily.
