Hair Loss Isn’t Always Hormonal: Your Sugar Intake Could Be the Reason

In the event that your hair suddenly starts losing its thickness or falling off excessively, it may not be just because of stress or hormone imbalances, but also because of excessive sugar in your diet. According to reports published in the Cleveland Clinic Journal of Medicine, excessive sugar intake can increase inflammation in the body and disrupt blood sugar levels, which directly impacts hair roots. In this situation, hair loss can be a warning signal, which, if ignored, can lead to a major problem later on.

The inflammation caused by sugar within the body also makes the hair dull and dry. The weakening of the keratin makes the hair more likely to tangle or break. Some people feel minor itching, while others' hair simply loses its elasticity. It becomes flat or limp.

Maintaining blood sugar levels is important for improving hair health. The selection of complex carbohydrates instead of refined sugars and refined flour can help. Fiber helps in slowing down the absorption of sugar. Drinking water is equally important. Proper hydration improves blood circulation and nutrient supply to the scalp. Use a mild shampoo and conditioner when washing your hair to protect the scalp's natural protective layer. Gentle scalp massage also increases blood flow and supports follicles. Don't neglect sleep and stress management. Regular sleep and stress-reducing habits maintain hormonal balance, strengthening the hair growth cycle.

Starting a very strict diet suddenly can be detrimental, as it shocks the body and can increase hair loss. Avoid excessive heat styling or chemical treatments if your hair is already weak. Relying solely on topical products isn't enough, as the underlying cause is often internal. Avoid hidden sugars in sweetened drinks, flavored coffee, or packaged juices.
