I would also add if it has any of that decorative cellophane on the pot keeping the water from draining, take it off. Lavender typically likes drainage. Another thing to note is usually the pretty potted flowers are sold just about when they are out growing their pot, so upgrading the pot could help if it's getting root bound (the roots are circling the inside of the pot).

Having said that, I strongly suspect lack of light. Lavender loves to be outside in bright sun, not stuck indoors in the shade.
