What are the signs of an unhealthy scalp, and do you think it effects your hair growth? Gym's comment about some people having scalp problems and not even knowing it made me think... I think some are completely internal (due to your diet, stress, level of health), some are completely external (chemical processing, too much tension), and some are a mixture of both. Here are some common scalp conditions that I see some women complain about on the board (please feel free to add): sensitive scalp (chemical, highly sensitive to too much manipulation) tight scalp dry scalp oily scalp flaky scalp itchy scalp dandruff excessive shedding alopecia thinning hairline/edges If you have had any problems with anything above (or anything I did not mention), please state which ones and how you prevent it or control it. Do you feel that your growth rate or texture of new growth has changed from dealing with it?
