Wondering why you still have lice if you’ve tried treating head lice on your own? It’s all about the eggs! Despite over-the-counter products claiming that they can kill lice and eggs, there’s nothing on the market that can penetrate the lice eggshell.
Unless all lice AND EGGS are eradicated, the lice infestation will continue. Lice will keep laying eggs and those eggs will hatch to lay more eggs. If even one egg is missed, the cycle doesn’t end.
