One of my case studies has dandruff and a dry scalp which is intermittently red/inflamed. He tells me it gets worse when he is under stress and can more or less clear up in the sun/when he's on holiday. He has thick hair which is normal/slightly greasy in type. Can anyone advise on what oil might help. I thought possibly coconut (though it is recommended more for dry hair) as it might ease the inflammation? has anyone used Brahmi - just read up on this one and thought it may also be one to try?
