Hair loss can be a scary topic to discuss. Although hair loss can happen after bariatric surgery, it is not permanent, and your hair will grow back. So why does this happen and what can you do to achieve great weight loss results and still have great hair?
The hair loss associated with weight loss surgery is called “telogen effluvium” and has to do with the normal hair growth cycle. It usually starts abruptly and very seldom lasts longer than 6 months.
Human hair has a three-stage growth cycle. The growth phase is called “Anagen” and 90% of our hair follicles are in this phase at any given time. Followed by “Catagen”, which last for 1-2 weeks wherein hair follicle detach from blood supply. The resting phase is called “Telogen”, which lasts about 1 to 6 months, with an average of 3 months and during this stage hair loss happens. About 5-15% of our hair is in the resting phase at any given time. The normal hair growth is around 1.25 centimetre or 0.5 inch per month or about 15 centimetres or 6 inch per year.
Research has shown that the physiological stress resulting from major surgery and from rapid weight loss can cause the body to shift nutrients towards vital organs such as the heart and brain and away from cosmetic functions such as hair growth. Although hair is important to us, it is not to the body. As a result, the hair growth phase could temporarily stop and the dormant state or resting phase set in, causing some hair loss to occur. Most commonly occurs at 3-5 months post-op. This is important because the hair in the resting phase at the time of surgery is most likely the hair you will shed. This is why your hair sheds between 1 to 6 months after surgery (usually about 3 to 4 months).
When the hair starts to grow again the old hair follicle is released and you lose hair. Sometimes the hair comes out before new hair grows.

Yes , as the body adjusts to the changes, the hair loss will decrease and then stop. Hair should grow back as normal as long as there are no nutrient deficiencies and you are consuming adequate protein.
So, what we have here are a few things that may be affecting people with hair loss. It starts with surgery, very low-calorie intake and possibly low protein intake. Then you add any illness along the way, an underactive thyroid, iron deficiency, or genetics and you get hair loss of about 5-15% of your hair follicles.
Other nutrients implicated in hair loss include zinc, biotin, folate, vitamin B-6 and essential fatty acids. If no deficiency of these nutrients exists, then they will likely be of little use.
