If you prefer the silky feeling (or just the convenience), it's completely fine to use 2-in-1 products. You just may need to add a clarifying shampoo once or twice a week. "The only downside to using a 2-in-1 is that the hair can begin to feel heavy over time," says Cardona.

Dollar Shave Club's supply model is also highly cost-effective. The company sources its blades and other men's grooming products from China and South Korea, and manages inventory from a single distribution center.

Dollar Shave Club spends much less on advertising and marketing. So Dollar Shave club can sell their blades for less. Dollar Shave Club doesn't manufacture anything. They buy their blades from suppliers outside the US.

General guidelines for hair washing frequency are as follows: Oily hair: Every day to prevent the buildup of dirt. Dry/damaged hair: Every 5-7 days to allow some of your hair's natural oils to be retained on the scalp. Fine/thin hair: Every other day to provide your hair with enough moisture.

Unlike double cleansing your skin, you shouldn't double shampoo daily. Over-cleansing your hair will eventually strip it of its natural oils and could lead to damage over time or cause your scalp to over-produce sebum (which then leads to dandruff and oily hair).
