Thinking about a business selling hair coloring products, or perhaps a shop that does hair coloring services, would it be a hit? I guess! Walking daily, I always notice about 50% of the individuals I've glanced have their hair colored. If there's an effective way to target the 50% then it would be an good investment for someone with keen interest in this niche. The problem though is that it's a common product or service in salons and beauty shops.
