A popular home fragrance product being sold within the last few years is the diffuser. It is usually a narrow glass bottle with esential oils filled inside. You then take bamboo reeds and place them in the jar to absorb the scent and lightly fragrant the room. They last for months and look very natural. Another type of diffuser goes on the end of the hairdryer. It is a large circular piece with spikes coming out of it. It gently separates the hair and dries it without making it frizzy. It is most often used on curly hair.
