The hair consists of 91% protein and amino acids, so when hair loses 30% of its proteins, it will be brittle and breaks easily and with time will become damaged and falling
How does hair lose its proteins?
Malnutrition
Hair straightening using chemicals
High heat by a frequent blow dry, ceramic hair ironing and other styling techniques
Dyes containing ammonia and its substitutes and bleaching compounds
Styling and care preparations containing harsh chemicals
Frequent exposure to the sun and chlorine
How can we compensate for the lost proteins?
Internally by eating high-protein foods such as eggs, fish, legumes, green vegetables, or to by external supplements approved by FDA
Topically protein-rich hair masks once a week or once-a-month or homemade organic masks.
Important note: Topical protein therapy does not smooth the hair, any hair-smoothing protein has anti-frizz end results is not a treatment but another chemical straightener named protein
