Chestnut Nano's, Colour Conversion: 2/4. 16” Nano’s: 21grams per pack, 30 pieces 20” Nano’s: 27grams per pack, 30 pieces We recommend 1/2 packs for adding thickness and 4/5 packs for a full head application adding thickness and length (depending on how thick the client’s hair is you may need more than 5 packs). Our remy hair can last for 9 months or MORE if the correct aftercare is utilised. The hair is double drawn; meaning the hair is the same thickness from root to tip as well as cuticle correct.
