Adding more essential oils to your wax melts won’t always be enough to improve the scent throw. If you are burning a wax melt and the scent is not strong enough, it is probably because there was an imbalance created in the recipe, with either too much wax or too little fragrance used. It can also be affected by the quality of the oils you used, which is why it is always important to buy from a reputable seller that can guarantee a better-quality fragrance.
