* Length: Longer hair is generally more valuable.
* Color: Virgin, natural, and rare colors (like true red or certain shades of blonde) often command higher prices.
* Thickness: Thicker hair is more desirable.
* Texture: Straight, wavy, and curly hair all have different values depending on current trends and demand.
* Health: Healthy, undamaged hair is worth more.
* Rarity: The rarer the characteristics of the hair, the higher the price.
* Demand: Current market trends affect prices.
Given all of those variables, 1 inch of hair is generally not worth much on its own. To get a significant amount of money, you typically need to sell a longer length (12 inches or more) that can be used for extensions or wigs.
If you're looking to sell hair, do some research on reputable online hair marketplaces to see what similar hair types are selling for.
