This way, the integrity of the hair and lace will be preserved. You may further specify extensive knot bleaching if you wish, but the knots of most wigs are bleached only along the hairline. You can achieve knot bleaching on your own following the instruction of the best full lace wigs maker strictly. If you have a level of lightness in mind, you can embark on DIY knot bleaching to achieve just that. For lighter color hair, knot bleaching may not be necessary since the knots are hardly visible.
Human hair lace front wigs promise perfect illusion of natural hair always, and you can wear just any hairstyle you desire, but wear only low ponytail and updo to prevent realistic hair-look alteration.
