Detailed answer

Hair products such as oils, gels, and sprays can contain comedogenic ingredients that clog pores and lead to the formation of whiteheads. These products can also create a barrier on the scalp or forehead, trapping sweat, oil, and dirt, which can further result in whitehead formation. Additionally, overuse or improper application of hair products can lead to an accumulation of product residue, exacerbating the likelihood of whiteheads. To prevent this, it is important to choose non-comedogenic or oil-free hair products and ensure proper cleansing of the scalp and face after product use.
