Excessive hair loss from weight loss is due to a condition known as Telogen effluvium.
These conditions usually disrupt the hair cycle. The hair grows constantly for two years at the rate of half an inch in length per month before it enters the resting stage known as Telogen. The constant growth and regrowth of the hair are due to the fact that all the hair is always at a particular stage. About ten percent of your hair at any given time is in the resting stage, the old hair falls out leaving room for new ones to grow. All these are carried out during the resting stages. Telogen effluvium occurs when the ten percent of the hair at the resting stage begins to multiply causing the hair cycle to be thrown off balance. Hairs fall out fasters than the rate at which it grows, meaning the rate at which the hairs fall out is greater than the rate at which it grows back.
Hair loss can also occur after weight surgery when your body undergoes surgery, it can lead to physical stress on the body, which then signals to the hair follicle to go into the resting stage. This is due to the hormone; weight loss surgery can lead to a big change in the composition of the body. The hormones need time to catch-up, but hair loss due to weight surgery is usually temporary, you can expect your hair to start growing within 2-3 months, or it can be supplemented with vitamins to revitalize the hair.
Another important thing to note is that your hair needs calories to grow, subsequently, most people who are losing weight achieve it by restricting their calorie intake. When your hair is not getting enough calories for it to grow, it becomes stunted and the begins to fall off. When going to a weight-loss session, you should understand your calorie limit so that you can have an idea of what to eat and how much to eat, this way the hormones can be balanced. One important fact to note when you are trying to stop hair loss is that the hair is made up of protein. Protein is readily available in our daily diet. Don’t panic when you are experiencing hair loss during weight loss, you don’t have a problem with your hair neither is your hair follicle damaged, your body is just trying to adjust to change and reduction in calories.
