If you decide to use a website

You can create a page with all the latest hair styles and list the products used to create those hair styles.

On the backend, sell all of the products used to create the hair styles, either as affiliates or from a dropshipper.

If you have the room to store inventory than you can even buy from a cheap wholesale source.

You can sell products to local beauty salons and barber shops.
Simply find a dropshipper or wholesaler that’s sells for cheap, sell cheaper than your competition, and boom…money in the bank.

If you have popular items, then you should list them on eBay as well.
They will for sure sell, all popular items sell on eBay.

You can make your own hair product catalog.
As stated before there are many different ways to make money selling hair products.

Let me know how this works out for you.
