I just stop my weight loss plan, and try to eat more and gain back some

另外我一直吃维生素矿物质片，感觉是低碳水的影响，也许我不对，看看专家意见，特

有个间接关系，是stress加大，造成hormonal的hair loss吧？
不知道你朋友是怎么论证的？
我觉得补VA，和增加睡眠，多休息，多喝水，适当增加热量就行了。

LOW CARB DIET & HAIR LOSS
0 COMMENTS
Jun 14, 2011 | By Julia Michelle
Low-carb diets limit carbohydrate intake by removing foods such as bread,
rice and pasta from the diet. These types of diet may also remove many
fruits, vegetables and whole grains. Depending on the type of diet chosen,
participants may consume large quantities of protein-rich foods, such as
meats, eggs and dairy to compensate for the missing carbohydrates. A
possible side effect of a low carb diet, according to After 50 Health, is
hair loss. To understand how a low carb diet might cause hair loss, one
should be aware of what hair is and how it grows.
HAIR STRUCTURE
Hair is composed of two parts: the strand and the root. The root is a small
bulb of living tissue that sits below the surface of the skin inside a
pocket called a follicle. The follicle provides the root with nutrients and
oxygen through a network of tiny blood vessels. The strand is the visible
part of the hair and is non-living tissue. The strand is made of long chains
of a protein called keratin and has three layers: the medulla, cortex and
cuticle. The cuticle is the outer layer of the hair, it resembles layered
scales and protects the cortex and medulla from damage.

HAIR GROWTH
Hair has two growth phases: The anagen phase and the telogen phase. During
the anagen, or growth, phase the hair grows steadily for two or three years.
During this phase, the hair can grow as much as 1/2 inch per month,
depending on heredity and other factors. During the telogen, or resting,
phase the hair stops growing for up to three months. Approximately 10
percent of all hairs go into resting phase, while the remaining 90 percent
stay in the growing phase. At the end of the resting period, the resting
hairs go back into the anagen phase, where new hair starts growing and
pushes the old hair out of the follicle.
DIETING AND HAIR LOSS
If the dieter consumes far fewer calories than the body needs, or removes
crucial nutrients, this creates stress. According to Dr. Michael Eades, the
stress from restrictive diets causes more follicles than normal to go into
the telogen phase. This may be because the body does not have enough
calories, or nutrients, to support the growth phase. Once the stress has
passed, the growth phase starts again and new hairs push out the old. If a
large percentage of the hair was in telogen phase, this results in massive
hair loss. Often, per Dr. Eades, the hair loss occurs months after the
dieter begins eating normally. This type of hair loss is called "telogen
effluvium."
LOW-CARB DIETS AND HAIR LOSS
Carbohydrates are calorically dense, and removing large quantities from the
diet also removes a significant source of calories. These types of diets may
also create vitamin and mineral deficiencies, depending on the severity of
the restriction. For example, Phase 1 of the Atkins diet allows several
salad greens but only allows 20 g of carbohydrates a day --- 300 g per day
is the typical recommended amount. Because the number of allowed
carbohydrates is so low, dieters may not consume enough fruits and
vegetables to provide enough nutrients.
CONCLUSION
The body uses carbohydrates for energy to fuel all the processes in the body
. Low-carb diets rob the body of its preferred fuel, forcing it to break
down fat for energy. Additionally, these diets restrict calories by removing
several foods from the diet. The combination of caloric and nutritional
restriction puts the body under stress, which can cause the hair to go into
telogen effluvium.
