I've said it before and I'll say it again; a good hair day is a good day which means confidence for me! A good hair day starts with GREAT hair care. But let's be honest. WHO has the time to go running from salon to specialty retailer to drugstore to find all of your favorite hair care items? I sure don't. That's why I STOCK UP on all of my must-have hair care items at Sam's Club.

Sam's Club is already one of my go-to shopping destinations; I seem to be at Sam's Club a lot. Not only do I have some of my hair care must-haves enrolled in Sam's Club Subscription Program (I love the large club sizes) they have other convenient shopping services that I take advantage of. When I am in a huge rush, I use Club Pick Up — SUPER EASY. But my favorite Sam's Club shopping service has to be the Scan & Go app. Why doesn't every store offer this shopping convenience?

Using the Scan & Go app is so easy. When I am in the club shopping around I just keep out my phone and open up the Scan & Go app. As I pick-up items, like my must-have Sam's Club hair care, I just scan the barcode on the item then place it into my cart. Then, when I am done shopping, I pay directly on the app. So easy. On the way out the door, I just show the digital receipt (on my phone) to the greeter.

Here is a screenshot of my app from a recent shopping trip.

Now, onto my Sam's Club hair care must-haves.

Depending on the time of year, I vary my hair care products. Just as I rotate my makeup and skin care according to the season, it is essential to my hair care routine that I change that up, too.

For instance, for my normal, everyday hair cleansing routine, I like Nexxus Therappe and Humectress. Both are formulated with Caviar and Protein Complex to lock-in 24 hours of moisture. I like how that the duo keeps my hair smooth without being weighed down, too. Both products are silicone-free.

During the summer, my hair is exposed to all the elements — the sun, wind, chlorine and salt. I need help protecting it and reversing the damage. I depend on TRESemmé Repair & Protect 7 Shampoo and Conditioner. Both the shampoo and conditioner are infused with biotin to help reconstruct damaged hair fibers from the inside out. When I use them together (they come bundled together in a club-size pack) my hair is strengthened against breakage and split ends. I like how my hair is left smooth, shiny and looking great every day.

During the cold weather, I like to use Suave Avocado + Olive Oil Smoothing Shampoo & Conditioner. This duo is salon proven to smooth hair and it does while keeping those winter frizzies and flyaways away. Don't you hate that? Made with 100% natural avocado and olive oil, which are known for their rich emollients, this fresh and gentle shampoo smooths as it cleanses. It literally leaves my hair touchably soft and smooth. When used as a total hair care system, Suave Professionals Avocado + Olive Oil gives me up to 10 times smoother hair vs a non-conditioning shampoo.
