Hair mousses and gels are popular because they are good styling and holding solutions, They can, however, aggravate acne and milia on the face and neck, particularly in areas the hair touches, such as the forehead, cheeks, and the back of the neck. Allergic reactions to the ingredients in these products can also occur.

Hair sprays may also cause allergic reactions and have been reported to cause irritation to the eyes, respiratory problems, and even irregular heart beats. When using hair spray the face should be protected, in particular the eyes, and care should be taken to not inhale the mist.
