For Dry Itchy Scalp: Mix 2 Tbsp fresh lemon juice, 2 Tbsp olive oil and 2 Tbsp water, and massage into damp scalp. Let mixture sit for 20 minutes, then rinse and shampoo hair. Treatment can be applied every other week.

For Limp or Fine Hair: Mix 1/2 cup flat beer (pour beer into a container and let it sit out for a couple of hours to deplete carbonation) with 1 tsp light oil (sunflower or canola) and a raw egg. Apply to clean, damp hair, let sit for 15 minutes, then rinse with cool water. Or add flat beer only to a spray bottle and spritz onto dry hair. When the liquid evaporates, the remaining protein residue (from the wheat, malt or hops) continues to strengthen and structure hair. Treatments can be applied every other week.

For Dry or Sun-damaged Hair: Massage approximately 1/2 cup honey into clean, damp hair, let sit for 20 minutes, then rinse with warm water. You can also add 1 to 2 Tbsp olive oil to loosen the honey for easier application. For extremely sun-damaged hair, trying mixing honey with 1 to 2 Tbsp of a protein-rich ingredient, like avocado or egg yolk, which will help replenish the keratin protein bonds that UV rays attack. Treatment can be applied once a month.

For Oily Hair: Pour 1 Tbsp cornmeal or cornstarch into an empty salt or pepper shaker and sprinkle onto dry hair and scalp until you’ve used it all. After 10 minutes, use a paddle hairbrush to completely brush it out. Treatment can be applied every other day.

For Frizzy Hair: Mash up half an avocado and massage into clean, damp hair. Let sit for 15 minutes before rinsing with water. Amp up moisturizing power by combining mashed avocado with 1 to 2 Tbsp of a hydrating ingredient, like sour cream, egg yolks or mayonnaise. Treatment can be applied every two weeks.
