Last year at my 30th birthday party, I asked 30 of my friends to share their beauty tips and tricks with each other. It was such a fun exercise to do, because as you can imagine, it resulted in a lot of laughs and great conversation. That moment was so memorable, that I decided to do the exercise again with a different group of girls at a recent event I hosted called Beauté for Breakfast.

My guests were all beautiful women in the beauty and fashion industry, who have not only great hair, skin, and nails, but also, great personalities and were more than willing to share with each other (and now you!) their most secret beauty tips you might not ever hear about from magazines or websites. Read below to learn some new tricks you can now start to incorporate into your own personal beauty routine.

Ditch your shampoo. Taye Hansberry swears by only using conditioner. Why? The idea is that over-shampooing your hair strips it of its natural oils.

Don’t wash your hair every day. Gretchen Rossi says that by washing the hair less often it helps preserve the natural oils in the scalp and keeps hair well moisturized.

Avoid clumps in your mascara by running it under hot water. Samira Radhemer says that by running her mascara wand under hot water before application makes the mascara go on smoothly and without clumps.

Use eyeshadow to cover gray hairs. Sydne Summer says that in between salon color appointments, she covers her pesky gray hairs with eyeshadow, the same color as her root.

Purple toothpaste to whiten teeth. Roz Saedi says that using purple toothpaste can whiten teeth. Purple is opposite of yellow on the color wheel, so the purple color corrects.

Use collagen powder to treat acne. Lauren Dailey cleared up her problematic skin by ingesting collagen powder every day.

Put oil in your hair before you wash it. Ravayna Coe uses apricot oil as a scalp treatment before she washes her hair.

Red lipstick will hide dark circles. Laura Albouy says that she puts red lipstick under her concealer to cover dark circles. Dark circles are usually blue or green in tone. If you look at a primary color wheel, the exact opposite of those colors are oranges and reds. Applying a bright red color underneath your eyes actually neutralizes the color you’re hoping to cover.

Use moisturizer to lighten up foundation. Samira Sedighan mixes moisturizer with her foundation if the shade is a little too dark, because the lotion lightens up the makeup.

Do an ice facial. Fernanda Romero says that her grandma never had any Botox, thanks to doing ice facials daily. Ice is said to improve circulation and restrict capillaries.

Oil for for overall health. Carly Sloane oil pulls every morning. Oil pulling is an ancient Ayurvedic dental technique that involves swishing a tablespoon of oil in your mouth on an empty stomach for around 20 minutes. This action supposedly draws out toxins in your body, primarily to improve oral health but also to improve your overall health.

Dye your eyebrows. Zia Domic says that dying her fair eyebrows saves her time because she doesn’t need to fill them in every day.
