A small amount of conditioner in contact with the scalp is generally harmless, but if a large number or long-term contact with the scalp may cause increased dandruff, hair loss, contact dermatitis.
Although the conditioner contains chemicals, but generally are up to national testing standards, a small amount of contact with the scalp generally does not cause harm.
However, long-term contact with the scalp of the chemicals in the conditioner may irritate the scalp and hair follicles, destroying the normal metabolism and leading to increased dandruff and hair loss.
The ingredients contained in different brands of hair conditioners may also vary, and if the patient is allergic to one of the ingredients, it may lead to contact dermatitis. Patients may experience discomfort such as redness, swelling, pimples and itching on the scalp.
Conditioner should be applied to the tips of the hair and rinsed with water if discomfort occurs after contact with the scalp. If the discomfort is not relieved, you can go to the hospital for treatment.
