If your locks are looking flaky lately, it’s due to rising temperatures and increased scalp oil production. For flake-free tresses mix 2 crushed aspirins into your shampoo and massage onto your hair and most of all, scalp, for 2 minutes before rinsing. You should see results in about 3 days. The salicylic acid in the aspirin sloughs off dead cells plus stalls the growth of yeast that causes flaky flare-ups.
