What is Brows Lamination? Brow lamination is a new, innovative beauty treatment that has continued to grow in popularity, recreating the trending look of thick, bushy brows. Brow lamination is great for those who love a ‘brushed-up' look but can’t seem to tame their brow hair due to it being too straight or fine. Generally, brow lamination lasts from four to six weeks. Depending on how well you look after your brows, it can last up to eight weeks. After the four to six-week period, it’s recommended that you get your brows re-laminated in order to maintain the look over a longer period of time.
