Questions & Answers
Wholesale Vendor FAQs
Sourcing & Processing
How is the hair collected?
We buy hair directly from women. We do not collect donor hair.
How is the hair sanitized and kept free of nits and lice?
We wash the hair with shampoo and dry it under the sun before processing. Nits and lice are removed by hand during quality control.
Which stages does your company do in-house?
We wash the hair, dry the hair, make weft bundles, remove nits and lice by hand, then wash and dry the hair again.
Which stages are outsourced, and how can you guarantee quality?
All processes are handled in-house. We guarantee quality mainly through hand-checking every single bundle.
Quality Standards
Can you describe the hair cuticle?
The hair is original human hair, so the cuticle is like natural human hair.
What percentage of the cuticles are aligned?
At the top, all cuticles are aligned. At the bottom of the bundle, it depends on the standard. For double drawn hair, about 30 cm of short hair is removed. For super double drawn hair, 75-80% of short hair is removed. Fuller bottoms can be made depending on price.
Is your hair tangle-free, odor-free, synthetic-free, and lice-free?
Yes.
Are the cuticles stripped to make different textures and curl patterns?
Our hair is original, so different textures can be made when needed.
Is the hair dipped in acid or ammonia?
No, we do not use acid for natural hair. For colored hair, acid is used during the bleaching process.
Are fillers added to the hair?
No.
Can you guarantee that your hair is virgin?
No. We can guarantee that our hair is 100% natural human hair.
Customization & Use
Can the hair be washed, conditioned, dyed, bleached, permed, relaxed, and straightened with heat?
Yes.
Can curly hair go back after being straightened?
Mostly yes.
How are the curls processed?
We use a steam water process for curled textures.
Is the hair 100g per wefted bundle, or 100g including packaging?
Each bundle is 100 grams without packaging.
Are the wefts double or single drawn?
We can make both double weft and single weft at the same price. Please note that double weft is shorter when you open the bundle.
Are the wefts created by machine or by hand?
Our wefts are machine-made.
Does the hair hold a curl using a flat iron, curling iron, or flexi rod?
For straight hair, no.
Can you customize a specific curl pattern?
Yes. We can customize curl patterns based on your pictures or sample. The process uses steam water.
What is the best way to store the hair?
Store the hair in a dry place.
How do you recommend maintaining the texture or pattern?
You can follow standard hair care guidance from trusted online sources. We mainly sell to wholesalers, not end users.
