Hair loss is a frequent occurrence among low carb dieters because of the increased stress that comes with large dietary changes. This is a temporary annoyance for keto dieters and a setback on the diet, according to the practices. Hair loss mostly happens three to six months after any major dietary change and only a small percentage of the hair falls out.
The condition is known as “telogen effluvium” and any major stressor can cause it including weight loss due to a low-caloric intake in keto diet. Another possible cause for hair loss on a keto diet is lack of protein in the diet as hair is made up mostly of protein.
Try to eat a balanced diet if possible and avoid stress. About 10 percent of those on extreme diet regimens can cause hair loss possibly due to a lack of nutrients like B vitamins and silica. There’s a belief that the ‘stress’ of ketosis (the principle by which fat is burned in keto diet) causes hair loss. As soon as you start keto diet, you can start taking supplements to avoid hair loss in the first place.
