Drawbacks

We found no evidence of drawbacks from combing alone, apart from discomfort for both the carer and the person being combed. Potential drawbacks exist for wet combing with conditioner, which requires conditioning crème rinses to be left on the scalp for prolonged periods, because adverse reactions to hair-conditioning agents have occurred after normal limited cosmetic use. Reactions include allergic contact dermatitis, urticaria, urticaria with systemic symptoms and angioedema.25-29
