The Normal Hair Growth Cycle has three Phases where it enters periods of growth and rest.
Anagen Phase
This is the hair growth phase and lasts an average of 3-7 years.
Catagen Phase
The catagen stage is a transitional period continuing for approximately 2-3 weeks and signals the end of the hair growth phase.
Telogen Phase
The telogen phase lasts around three months, where the hair goes into a period of resting. It's then released, falls out, and the entire growth cycle begins again. Each hair follicle is independent and transitions through the cycle at different times. Approximately 10-15% of hairs on the scalp are in the telogen phase.
What causes Postpartum Hair Loss?
During pregnancy, the increase in blood circulation stimulates hair follicles, and the rise in the hormones, oestrogen and progesterone, prolongs the hair growth phase (anagen) and delays the shedding phase (telogen). This results in the thicker, glossier hair that women experience in pregnancy.

After childbirth these hormones drop, level out, and typically around two to three months postpartum, many new mums begin to notice that they are losing hair. This is just the extra hair that was gained during pregnancy and shedding these additional hairs is a normal part of the body returning to its pre-pregnant state. The good news is the normal hair growth cycle typically returns 6-12 months after childbirth.
The degree of hair loss will vary from person to person, but if it worsens or persists beyond a year postpartum, its important to seek advice from a Doctor who may suggest investigating vitamin D, iron and thyroid function.
Why is Nutrition Important?
Pregnancy, childbirth and lactation are considerably demanding of maternal energy and nutrients stores and it's vital to replenish them with all the goodness that real food provides. During pregnancy and breastfeeding, a number of hair-supporting nutrients are particularly vulnerable to depletion. This includes iron, zinc and omega 3 fatty acids.
For most people, following a wholesome, balanced diet supplies all the nutrients they require - incorporating varied sources of high quality lean protein, healthy fats and an abundance of nutrient-dense vegetables.
Four Key Nutrients to Support the regrowth of Hair
Protein supplies the body with amino acids, which are the building blocks for keratin; the structural material of hair. In total, there are twenty amino acids. Although they all participate in tissue growth and maintenance, some have specific roles of their own. For instance, cysteine provides sulphur to hair cells and lysine stimulates collagen production. Collectively, they enhance texture, elasticity and the regeneration of the hair.
Food sources: organic grass fed lean meats, eggs, fish, quinoa, yogurt, beans and pulses.
Healthy fats are an excellent source of oils that enhance sebum secretion to nourish and hydrate the scalp. Food sources: avocado, nuts, seeds, mackerel, salmon, herring.
Iron is used to synthesise red blood cells that transport oxygen around the body. A lack of iron can effect the amount of oxygen and nutrients reaching the hair follicles, and in its absence, hair follicles aren't able to function optimally. Food sources: organic lean grass-fed beef, beans, lentils, green leafy vegetables
Vitamin C is a powerful antioxidant that may protect hair follicles from oxidative damage. It also enhances the intestinal absorption of iron and acts as a mediator for collagen synthesis. Food sources: citrus fruits, peppers, broccoli (in addition to Zinc , Vitamin D, Vitamin A, B Vitamins and Omega fatty acids)
