Detailed explanation-1: -These are made up of proteins like elastin, collagen, and keratin. When your body can’t make them, you could have brittle or thinning hair, dry and flaky skin, and deep ridges on your fingernails.

Detailed explanation-2: -Serious protein deficiency can cause swelling, fatty liver, skin degeneration, increase the severity of infections and stunt growth in children. While true deficiency is rare in developed countries, low intake may cause muscle wasting and increase the risk of bone fractures.

Detailed explanation-3: -The longer the cuticles are raised up, the longer the cortex of the hair is exposed and, therefore, makes the hair more susceptible to protein loss and breakage.

Detailed explanation-4: -Hair loss may occasionally be caused by lack of protein in the diet. Some people who go on crash diets that exclude protein or who have abnormal eating habits may develop protein malnutrition. When this happens, the body will help save protein by shifting growing hairs into the resting phase.

Detailed explanation-5: -[3] A low intake of dietary protein can lead to brittle hair and slow hair growth as the body lacks the amino acids required to support healthy, strong hair. [4] Research suggests a lack of protein in the diet contributes to thinning and even hair loss.
