* Length: Longer hair is worth significantly more.
* Color: Natural, rare colors (like certain shades of red or virgin blonde) are more valuable.
* Condition: Virgin hair (untreated, uncolored, unpermed) in excellent condition is the most sought-after.
* Texture: Specific textures (e.g., fine, thick, curly) might be in higher demand.
* Market: Prices fluctuate based on current trends and buyer demand.
However, 40 grams is not much hair, regardless of the price and would be priced significantly lower than longer lengths.
