Haircare, there are a million brands to choose from. It can really be overwhelming at times. If you are like me you have a cabinet or shelf full of half-used products. Not anymore, I found Theorem. Theorem was developed by a team of women scientists wanting to bring their knowledge and expertise to you at home. Theorem by Carrie Kelly Lifestyle is the best hair care you won’t find in a salon. The Theorem Method started it all (read more about the method HERE) and the line has expanded to include shampoo, conditioner, and more styling products. Great but what Theorem shampoo and conditioner should I use? I’m here to break the lines down.

Let’s start with the Volume Line. No need to have boring flat hair. Pump up the volume with this gravity-defying, anti-pollutant shampoo and conditioner that builds volume over time with every wash. Give your hair the depth it needs and the height it desires with this gentle lightweight shampoo. Follow with this 3-dimensional Conditioner that takes your hair to new heights and won’t weigh down your hair. Volume’s gentle formula adds body, texture, and shine after the first use.

For dry and damaged hair, let’s check out Infinity. Dry, damaged, and frizzy hair all have one thing in common, lack of hydration. Give your hair the quality of being infinitely shiny, hydrated, and soft with Theorem’s Infinity shampoo and conditioner. Your hair will have boundless amounts of sparkle and bounce from the sealed in moisture. Say goodbye to frizz and hello to smooth beautiful hair.

For the blond girls like me keeping hair from turning brassy is a constant battle. Spectra is the answer. Revive your blonde, highlighted, platinum, and silver hair by enriching the color to correct yellow and brassy tones. Take your hair to a new level of brightness with Spectra Duo. Don’t let your hair feel dry and brittle because of coloring and heat damage as a blonde. Spectra uses a special complex of Chamomile, Vitamin E, and Folic Acid to nourish the hair from the outside in. Look out for soft, toned, beautiful golden locks.

Curly hair has unique needs too. Helix and Spiral to the rescue. Over time, curls and waves can lose their bounce and shine. Helix will transform curly, wavy, coily, and porous hair with its unique 2-in-1 formula of being a conditioner with just a touch of cleanser. The Helix cleansing system removes dirt, oil, and pollution without stripping the hair of its natural oils. From root to tip your hair will flourish with our unique blend of Coconut Oil, Essential Fatty Acids, and Rosebay. I love a cleansing conditioner so I use this one too. Meet the ultimate hydrator – Spiral Leave-in Conditioner quenches dry hair with Coconut Oil working to restore moisture and boost elasticity for beautiful, hydrated, frizz-free curls. With curly and wavy girls in mind, Spiral can be used from root to tip to ensure the most beautiful natural texture. This product really goes the extra wavelength nourishing dry hair and making your hair more manageable with fewer tangles. As an added bonus, Spiral supports a healthy, balanced scalp. I love this ultra-hydrating conditioner.

Theorem has a system for every hair type and need. Theorem Method hair care products are sulfate-free, paraben-free, gluten-free, phthalate-free, cruelty-free, and vegan. Want to know my secret? I actually combine different shampoos and conditioners on different days depending on what my hair needs are on that particular day. I will use a pump of Spectra shampoo with a pump of Volume shampoo or vice versa. Same with the conditioners. I always use a little Density Treatment Mask in my conditioner too, it is botox for the hair. Learn more about Density HERE. I use only Density as a hair mask every 3 washes. Theorem makes hair care easy and personal. Combine the products for your best fit. Still want to know what duo is right for you, take the style quiz HERE or send me a message HERE.
