Brondie Weft, Colour Conversion: 4C/8. All 50-gram lengths are 50 grams per pack. We recommend 3-4 packs for a full head fitting to add thickness and length. 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. For colour matches please email [email protected] or DM us on Instagram @spectrumonehairextensions If you are a retail customer and would like to have our extensions fitted, please contact our salon on 01706 216808 or go to our website http://spectrumonesalon.co.uk/ where one of our lovely team will be happy to help you. You can book in for a free consultation to discuss what options would be the best for you and they will help you achieve your hair goals.
