From personal experience, I found that hair health is really a combination of both internal and external factors. While many believe that diet and vitamin deficiencies are the main reasons behind hair problems, it’s essential first to get proper blood tests to verify whether you have any deficiencies. I followed this approach by consulting my doctor and confirming that my vitamin levels were normal. Yet, despite good internal health, I still struggled with hair breakage and dryness for a while. It wasn’t until I re-evaluated my hair care routine and switched to gentler, nourishing products that I noticed a significant improvement. Using shampoos and conditioners with moisturizing ingredients, as well as avoiding harsh heat and chemical treatments, helped restore my hair’s shine and strength. Another factor to consider is lifestyle. During periods of stress or less physical activity, hair quality can suffer — not merely because of vitamin deficiencies, but due to hormonal shifts and cortisol levels. Maintaining an active lifestyle and managing stress helped me maintain healthier hair over time. In summary, while internal health is important and worth checking through blood work, your hair care products and lifestyle choices often have a larger impact on hair health than people realize. Regularly reviewing both internal health markers and external hair care habits can help anyone achieve their healthiest hair growth and maintain optimal hair density and shine.
