How Food & Your Diet Affects Your Hair - Hair Nutrition | Philip Kingsley

General Health and Your Hair

Last Reviewed: October 2021


Your hair is extremely sensitive to internal changes within your body. But why is this? In part, it’s because hair cells are our second fastest dividing cells, second only to intestinal cells. However, because hair is deemed non-essential tissue (unlike your liver or kidneys, for example) its high energy needs are never given priority. This means your hair is usually the first thing to suffer from any bodily upset, yet also the last to benefit from any improvement.

Your hair can be affected by an extremely wide range of health-related factors, including:

  • Stress and anxiety
  • Nutrition and diet
  • Sleep patterns
  • Pregnancy
  • Menstrual cycle
  • Menopause
  • Long-term illness
  • Short-term illness
  • Fever
  • Surgery
  • Medications


It is important to note that hair loss does not always coincide with the disturbance that caused it. Due to the nature of the hair growth cycle, it is likely to take 10-12 weeks before the effects of an illness or trauma are noticeable in your hair. If you are experiencing excessive hair shedding, have a look back two to three months to help identify any possible triggers.

Here at Philip Kingsley, we adopt a holistic approach to hair care. When Clients seek help from us, our Trichologists investigate all factors that could be affecting their hair. Besides examining the hair and scalp in detail, we also take a deep dive into your diet and lifestyle, as well as medical and family history. In some cases, we also request blood tests for a more in-depth analysis of a Client’s overall health.
