When you want to keep frontals in place, glue and gel, have good and bad sides. Picking the better one depends on your life, how your skin reacts, and how long you want the frontal to stick.

Glue holds strong and lasts long. It's perfect if you wish your frontal to stay for many days or weeks. Most glue lasts through sweat and water, which is good for busy people. But, glue can be hard on the skin, especially if your skin is easily upset or if you have allergies. Messy use or removal might hurt your hair or the skin around it.
The gel is a gentler way. It’s nice for quick wear, like a style for one day or an event. The gel is easy to put on and take off, and it usually doesn't cause harm to hair edges as glue might do. Gel also allows more freedom and can feel nicer. Yet, the gel doesn't hold as long and may not stick well in wet air or sweat.
So, glue is best for firm, lasting hold, and gel is good for short use and simple taking off. Some folks use both—gel for the edges to look natural and glue for the main grip.
If you’re new to frontals or worried about your skin's reaction, trying gel first might be wiser. No matter what you pick, follow the steps right for putting on and taking off to shield your skin and hair edge. Always test a small bit to keep away from problems.
