Tracey Walker from Peterborough is a trichologist. This is someone who specialises in a form of dermatology, dealing only with the hair and scalp. 

Speaking to the Peterborough Telegraph, Tracey’s advice for healthy hair is:

1. Watch your diet, as this can play a huge part in the health of the hair. You need to eat a varied diet, protein with every meal and lots of fruit and vegetables.
2. Shampoo and condition your hair regularly. Unwashed hair gets a build up of yeast and bacteria on the scalp which can trigger problems there such as eczema. People with scalp problems or oily hair will probably need to wash their hair daily or every other day.
3. Be careful with chemical processes and heat. Be cautious – use straighteners in moderation.
4. Get a good hairdresser who is knowledgeable about hair care.
5. Use the right products, as this will help you get a lot more out of your hair.

Hair loss can be a distressing experience, and one worth avoiding if at all possible. "I've had patients come in that won't go to the hairdressers, that won't even go out because their hair is thinning. It can really take over their life, they get really distraught," said Tracey.
