Two of my new favorite shampoo-free or gentle-shampoo-only itchy scalp treatments and one more tentative idea. If you have itchy scalp, itchy or sore little bumps on your scalp or hairline or dandruff, some of these might work for you. I prefer shampoo-free treatments because most dandruff shampoos are very irritating to skin that is already quite irritated and can be drying -which just causes more problems. ©Science-y Hair Blog 2013 - Sulfur:  1/4 teaspoon colloidal sulfur (liquid) mixed into 1 tablespoon water or whatever liquid you choose yields a  2% solution - approximately. (1.25 grams in 14 grams). If this is too strong, use half the amount of sulfur. Apply to dry scalp with an eye dropper, or a bottle with a dropper-type opening (like an eyedrop bottle) leave on for about 5 minutes, then cleanse scalp and hair.  Do not leave this on, it needs to be washed off.  Lately I mix this into a pre-made plain gel base instead of water and dip my fingers in it to apply...

Itchy (and dry) scalp is often accompanied by flaking skin Also see this newer post for some new ideas ! Itchy Scalp can have lots of causes. "Dandruff" refers only to the flakes, not the cause of the flakes. Seborrheic dermatitis, also known as Seborrheic eczema is eczema, or a recurring inflammation (causing itching, rashes, scaling or "flaking") of the skin on oilier parts of the skin such as your scalp, eyebrows, face, chest. Most often associated with allergies, you can develop Seborrheic dermatitis as a result of contact with chemicals or friction on the skin. Once your skin has become inflamed and irritated, it's "waterproof" barrier has broken down - tiny cracks open up and allow chemicals through where they can cause further irritation. Elsewhere on your body, eczema usually looks like dry, red, flaky patches that don't become smooth or soft no matter how much skin lotion you apply. They may crack and bleed or get "weepy" and bli...

I work outdoors, sometimes all day for a week at a time in spring, summer or autumn. So I know a thing or two about what makes an ideal hat. What does this have to do with hair, skin and the meaning of life? Bear with me, please. 1) A proper hat protects your eyes. Shading the eyes prevents migraines, cataracts and squinting which can cause headaches. ©Science-y Hair Blog 2013 2) A good hat keeps the sun off your scalp and hair. Hair protects the scalp. Hats protect the hair and scalp.  When hair is exposed to 200 hours of ultraviolet radiation from sunlight, the cuticle edges begin to fuse as the cuticle “shrinks.” As it shrinks, tiny openings are created and these are known as "porosities." After 400 hours, porosity continues to increase with further cuticle damage, and after 1200 hours, the cuticle becomes rigid, brittle, and may crack, leading to even further increases in porosity. If your hair grows the "average" of up to 6 inches per year (15 cm) and you get s...
