Page 38 - The Law of Lashes Ultimate Lash Ebook

Lash growth is affected by many factors, such as :

hormone levels (for example, pregnancy and thyroid)
medication (thyroid abnormalities have been found to strongly associate
with hair growth)
diet and vitamins
amount of sunlight
lash serums
Lashes are not only hormone-dependent structures, but they also produce a
variety of hormones acting in:

1. paracrine (a form of cell-to-cell communication in which a cell produces a
signal to induce changes in nearby cells)
2. autocrine (a form of cell signaling in which a cell secretes a hormone or
chemical messenger that binds to autocrine receptors on that same cell,
leading to changes in the cell)
3. or intracrine (a hormone that acts inside a cell, regulating intracellular
events) manner therefore causing changes directly in the skin and hair
biology.
HAIR GROWTH DURING PREGNANCY

If you have had children or pregnant customers, you have probably noticed a
change in their lash retention and overall lash health. These are both affected
by the changing hormones in women’s bodies during pregnancy and
breastfeeding and also the extra folates they take.

Folates are responsible for stimulating hair follicle cells’ rebuilding, preventing
hair from falling out, and regulating sebum glands functioning. Here are some
great folate sources: kale, asparagus, white beans, Brussel sprouts, green peas,
beets, cod, halibut, eggs, and poultry liver.
THYROID ABNORMALITIES

The thyroid hormone influences the activity of all cells in humans. It is
therefore not unexpected that hair follicle activity is affected by hypothyroidism
or hyperthyroidism. Hypothyroidism causes hair to become dull, brittle, and
coarse with a reduced diameter as well as areas with hair loss. Hyperthyroidism
can cause hair to break off and to become shorter; it can also cause Alopecia.

It has also been found that skin thickness contributes positively to vitamin D
status, so using medication that causes thinning of the skin will also decrease
vitamin D status. Also, age plays a part because aging reduces skin’s efficiency
in vitamin D synthesis.
