Hair and nails
Hair and nails work with the skin to protect our body tissues from injury and help regulate temperature. They may be affected by nutritional deficiency, ageing, injury or infection.
Itching scalp can be caused by a number of conditions, including dandruff, seborrhoeic dermatitis and psoriasis.
Most men and women are affected by hair loss at some stage in their life.
No product can prevent head lice, but regular checks can help prevent the spread.
Pubic lice (crabs) are spread through skin-to-skin contact and can cause small red areas or sores and itching.
