Three Spa Treatments Made From Kitchen Scraps

Overripe bananas aren't just good for banana bread; used topically, their amino acids have been shown to increase the diameter of individual hairs and boost blood flow to follicles to encourage healthy growth. Use them with olive oil and honey for instantly full, lustrous locks. Mix half of a mashed banana with 1 Tbs. of olive oil and 1 Tbs. of honey. Apply to damp hair from roots to ends. Let sit for 20 minutes, then rinse.

Even if it's lost its crunch, the veggie is packed with anti-inflammatory properties that calm the redness and itchiness that comes with inflamed skin. For even speedier results, mix with skin-soothing and moisturizing aloe. Puree 2 stalks of celery in a blender. Strain, then mix the liquid with 1/4 cup aloe vera gel. Rub onto irritated skin and let sit for 10 minutes, then rinse.

Egg whites are packed with proteins that have a tightening effect on skin, while their amino acids promote collagen and elastin production to help lax areas look more taut. Pair with yogurt (its lactic acid gently exfoliates) for smoother skin in a flash. Mix 1 egg white with 1 Tbs. of plain yogurt. Apply to saggy skin spots like the chest and neck. Let sit for 15 minutes, then rinse.
