got questions?

I’m not sure what my hair profile is - help!

Of course - here are some more in-depth descriptions of each part of the hair quiz:

hair type

  • Straight: Hair strands tend to not have a bend or a curl. Hair Type 1
  • Wavy: Somewhere between straight and curly. Hair Type 2.
  • Curly: Defined curl, S-shape, or loopy pattern. May be prone to frizz. Hair Type 3
  • Coily: Tight curls, spirals, or zig-zag patterns. Sometimes referred to as “kinky” or “textured” hair. Hair Type 4.

hair structure

  • Fine: A single strand is thinner than a sewing thread. If you take a strand of hair between your fingers you don't feel anything.
  • Medium: A single strand is about the thickness of a sewing thread. If you take a strand of hair between your fingers you can feel the hair.
  • Coarse: A single strand is thicker than a sewing thread. If you take a strand of hair between your fingers you can feel a strong, thick strand.

scalp moisture

  • Dry: Your scalp might be dry or flaky. You typically wash every 3-4+ days.
  • Normal: Your scalp is about the same a day after you wash it.
  • Oily: You feel the need to wash your hair daily.

What are the fragrances like?

We like to think we have something for everyone. Our signature fragrances are:
  • nude (p)each: Top Notes: peach nectar, mandarin, lemon zest, jasmine. Reminds us of: cutting up fresh, juicy peaches on a hot summer day
  • (pear)fection: Top Notes: pear, apple, sweet musk, subtle florals. Reminds us of: biting into a juicy pear on a crisp fall day.
  • all (you)calyptus: Top Notes: eucalyptus, mint, lavender, rosemary. Reminds us of: an exhilarating hike through the misty mountain tops
  • strike a (r)ose: Top Notes: Rose, black currant, sandalwood, orange blossom. Reminds us of: A cool, modern rose fragrance with a bit of edge
  • true l(o)vender: Top notes: Lavender, Eucalyptus, Bergamot. Reminds us of: Relaxing in your clean sheets after a hot shower.
  • floret: Top notes: Gardenia, rose, sandalwood, amber. Reminds us of: A memory of the seasons changing and flowers growing.
  • fragrance-free: A great option for those with sensitivities

Do your products work for all ethnicities?

Absolutely! Every single one of our products is individually filled and formulated based on your unique hair type and hair goals, which means they’ll actually work with your hair, not against it. We also never formulate with sulfates, parabens, phthalates, mineral oils, or gluten, so you can rest assured knowing that all of our products are safe and effective, regardless of your ethnicity or hair type.

How do I choose my hair goals?

You can give your hair care formula an extra boost by choosing up to five of our 18 hair goals:

  • Strengthen: Increase your hair's natural resilience and elasticity, stimulate healthy hair, and help protect your hair from future breakage.
  • Anti-Frizz: Nourish and soften the hair texture for a smoother appearance, while also protecting strands from added frizz, static, and breakage.
  • Color Protection: Protect your hair from damaging UV rays, prevent dulling and fading, and enhance your strands' color retention to promote long-lasting, vibrant color.
  • Curl Definition: Enhance and define your natural curls to achieve a smoother texture and improve their overall health and manageability.
  • Deep Condition: Moisturize and deeply condition your hair from the inside out to help repair damage caused by heat and chemical processing. (*Best for those with wavy/curly, coarse, dry, or damaged hair.)
  • Fix Split-Ends: Smooth, coat, and seal your split ends to create a sleek finish while also helping to prevent new split ends from forming.
  • Hydrate: Restore your hair's natural moisture balance, prevent future moisture loss, and help treat damage with an added dose of long-lasting hydration that won't weigh your hair down.
  • Replenish Hair: Replenish nutrient-depleted strands, reverse damage, and help protect your hair from environmental stressors with a unique blend of high-quality hair ingredients.
  • Shine: Enhance your hair's natural shine and luster, while also improving your overall hair health.
  • Straighten: Relax and tame unruly hair with a biolipid complex that coats each strand in a sheathing film to help naturally discipline hair even in humid conditions.
  • Thermal Protection: Moisturize and condition heat damaged hair while also protecting strands from future damage caused by thermal styling.
  • Volumize: Rejuvenate limp, lifeless strands and remove excess buildup to help inject your hair with added body and lift.
  • Lengthen: A blend of high-quality ingredients, including pea sprout extract and blue-green algae, helps promote scalp circulation and follicle stimulation for stronger, healthier-looking hair.
  • Oil Control: Stimulate and revitalize your scalp to help prevent excessive oil production for healthier-looking hair.
  • Soothe Scalp: Moisturize and energize your scalp to help relieve discomfort, reduce buildup, and prevent dry, itchy flakes.
  • Nourish Roots: Stimulate your hair roots and facilitate the transport of key nutrients to the hair shaft to promote healthier-looking hair.
  • Anti-aging: Revitalize and strengthen your hair to help prevent premature aging caused by environmental stressors, heat and chemical styling, and nutrient loss.
  • Reduce Brassiness: Deep purple pigments neutralize brassy (yellow/orange) tones to help promote brighter, more vibrant looking blonde hair, while also extending the life of your color. (*Note: This is a purple-colored shampoo, which is designed primarily for those with natural blonde, color-treated, bleached, highlighted, or gray hair.)
