Brow lamination is a beauty treatment that involves straightening and lifting the brow hairs to create a fuller and more defined look. The process typically involves the use of a perm solution containing active ingredients such as Ammonium Thioglycolate, which temporarily straightens the hairs. The treatment usually consists of several steps, including the application of various solutions and the use of tools like spoolies and combs. After the lamination process, it is recommended to keep the brows dry and avoid water and steam for 24 hours. Some kits also include a treatment oil to be applied after the process. The ingredients in brow lamination kits can vary, but they often include chemicals like thioglycolic acid or ammonium thioglycolate, which are used to break down the bonds in the brow hairs and reshape them. While some products claim to have relatively minimal chemicals and be safe for at-home use, it is important to follow the prescribed directions and be aware of the potential for skin irritation. Examples of ingredients in professional brow lamination kits include water, cysteamine HCl, cetearyl alcohol, and various other compounds. It's worth noting that there isn't a "clean" or natural brow lamination option available, and ingredient disclosure is not always required for these products.
