How Hair Protein Works: 3 Steps for Stronger, Fuller-Looking Hair
Your hair is made up of approximately 90% protein — but when you consume everyday dietary protein, your body decides where those nutrients are needed most, and your hair isn’t always first in line. Here’s how arrae Hair Protein finds its way straight to your strands.
Build Stronger Strands
The Ingredients:
Hair Protein Complex™
-
Ovitage® Kinetic (Specialized Keratin Peptides)
-
Type I & III Bovine Collagen Peptides
What They Do:
Specialized keratin and collagen peptides give your hair the amino acid building blocks it needs to look and feel stronger and more resilient. Ovitage® Kinetic delivers keratin peptides rich in cystine, which can help support the connection between your hair and follicles, while collagen peptides help support the structure surrounding the follicle and maintain a healthy scalp environment. Together they create a solid foundation for healthy hair growth.*
The Research:
Your Hair Needs Protein To Build Protein
Hair is primarily made of keratin, a protein built from amino acids. Ovitage® Kinetic and collagen peptides provide key amino acid building blocks that give your body the raw materials it needs to make proteins like keratin, helping support stronger, more resilient-looking strands.*
Activate Healthy Growth
The Ingredients:
-
Pea Sprout Extract
-
Lustriva® (Magnesium Biotinate + Silicon)
-
Spermidine
What They Do:
These growth-activating compounds help sustain the right environment for healthy hair growth, complementing the structural support provided by key proteins. Together, they help support stronger, healthier-looking strands from root to tip.*
The Research:
95% Experienced Reduced Hair Loss After 2 Months
In a clinical study on Pea Sprout, 95% of participants experienced a reduction in measured hair shedding after 8 weeks.*†
18% Increase In Thicker Hair In 21 Days
Lustriva® has been clinically studied to support measurable improvements in thicker hair in as little as 3 weeks.*†

Protect The Process
The Ingredients:
-
Micronutrients (Vitamin C, B3, B5, Zinc)
-
KSM-66® (Ashwagandha Root Extract)
What They Do:
Defending the environment that healthy hair is built on is a crucial step to improving hair health. Micronutrients support a healthy scalp environment while Ashwagandha Root Extract supports stress resilience and improved sleep quality — factors that can play a role in stress-related hair shedding or thinning.*
The Research:
Up to 16.4% Reduction in Serum Cortisol
KSM-66® supports cortisol balance to help with stress resilience & sleep — key factors that can impact the hair-growth cycle.*†
Up to 35.2% Increase in Sleep Quality Scores
KSM-66® supports improvements in sleep quality, a critical component of the hair growth process.*†
BONUS Section: The Key Nutrients for Hair Health
What are the best nutrients for hair growth? We picked the four key micronutrients worth knowing: Vitamin C, B3, B5, and Zinc.
Vitamin C helps support collagen formation and protects cells from oxidative stress, Vitamin B3 and Vitamin B5 support cellular energy metabolism, and Zinc supports normal cell growth, tissue repair, and protein production — all key players in healthy hair growth.

What Makes arrae Hair Protein Unique?
arrae Hair Protein goes beyond traditional hair vitamins with a protein-powered formula designed to support healthy hair from root to strand.
Hair is approximately 90% protein, but your body prioritizes dietary protein for essential functions before sending it to your strands. That’s why Hair Protein takes a more targeted approach, using specialized keratin + collagen peptides designed to deliver specific building blocks your hair can recognize and use. Alongside clinically studied ingredients that support healthy growth, reduced shedding, and overall scalp health, it’s targeted support for stronger, healthier hair — with Lustriva® helping you see thicker, fuller-looking hair in as early as 21 days.
And unlike the pills and gummies crowding your supplement drawer, Hair Protein comes in a delicious lemonade-flavored stick pack you’ll actually look forward to drinking every day. It’s all-in-one hair support, made refreshingly easy.*

Understanding Hair Growth & Loss
What Is the Hair Growth Cycle?
Each hair follicle moves through three main phases that make up the hair growth cycle: anagen (active growth), catagen (transition), and telogen (resting and shedding). Factors like stress, hormonal changes, aging, and nutrition can influence this cycle — including how long hair stays in the active growth phase before moving into the shedding phase.
That’s why supporting a healthy hair-growth cycle matters. Hair Protein combines clinically backed ingredients with targeted protein and nutrient support to help maintain a healthy growth cycle, including supporting the active anagen phase — so you’re supporting healthy hair from the root as it grows.*
Why Does Hair Shed or Thin Out?
The health of our hair has more to do with our lifestyle choices than we think. Think of it like your skin: poor sleep, an imbalanced diet, stress, and more can all show up in the way your skin looks and feels. The same goes for your hair.
These are some everyday factors that can influence the hair growth cycle and contribute to increased shedding or breakage:
-
Stress: Physical or emotional stress can influence the hair growth cycle and lead to more noticeable shedding.
-
Poor sleep: Consistently skipping out on a good night of sleep can affect the way hair grows and repairs.
-
Nutrition: Hair needs protein, vitamins, minerals, and other nutrients to build strong strands. Not getting enough of what your hair needs can impact growth and overall strength.
-
Major changes in your routine: Travel, intense training, significant dietary changes, or other shifts in your day-to-day can put additional stress on the body.
-
Perimenopause/menopause: Changing hormone levels during this stage of life can affect the hair growth cycle, potentially leading to increased shedding and overall hair loss.
-
Postpartum: Hormonal changes after pregnancy can also affect hair growth and increase loss.
-
Hair habits: Frequent heat styling, chemical treatments, tight hairstyles, and more can weaken strands and contribute to breakage, making hair look thinner over time.
While we know these lifestyle factors can play a role, that doesn’t mean it’s always easy to pinpoint the root cause of hair concerns. Hair shedding and thinning can be due to one of these, or a wide combination of factors — which is why comprehensive support matters. Instead of focusing on just one piece of the puzzle, you want a formula that supports your hair from all angles.
How Can You Make Hair Grow Faster?
DYK: When it feels like your hair just “isn’t growing,” it could actually be because it’s breaking off at the ends?
You can’t change your hair’s natural growth cycle, but you can help optimize how your hair grows. Providing the nutrients your strands need can support stronger hair, reduce breakage, and help you retain more of the growth you naturally achieve.*
What Are the Best Ways to Naturally Stimulate Hair Growth?
While you can't speed up the hair growth process, there are plenty of ways to naturally support the conditions that promote healthy hair growth like diet, sleep, scalp health, and more.
-
Scalp Massages: Gentle massages can temporarily increase blood flow to promote an oxygen-rich environment for the follicles.
-
Hair Oils: Oils can help nourish the scalp and protect strands from dryness and breakage, creating a healthier environment for your hair to thrive.
-
Eating Enough Protein: Hair is made up of 90% protein, so getting enough in your diet can help your hair stay healthy & strong,
-
Quality Sleep: Without quality sleep hair follicles can’t get the ample energy they require during the growth phase.
-
arrae Hair Protein: A targeted protein complex and clinically studied ingredients deliver the structural building blocks and comprehensive support needed for healthy hair growth.

How to Get the Most Out Of Hair Protein
Your path to endless good hair days starts now! This mini-guide offers our favorite science-backed suggestions for maximizing thicker, stronger, fuller-looking hair.
-
Stay Consistent: Taking Hair Protein daily is the key to unlocking all the benefits. Make it the newest staple in your morning routine, your fun lunchtime bev, a 3pm pick-me-up, or even your new lemonade-flavored nightcap. The best time to take it? Whenever you’ll be looking forward to it most.
-
Sleep with Silk: We sleep for nearly a third of our lives, so protecting our hair while we do it is crucial. Silk pillowcases and bonnets are a great way to minimize damage overnight, and they’re good for your skin, too!
-
Scalp Massages: Think of it as a mini workout for your scalp — gentle massages help stimulate circulation and create a more nourishing environment for your follicles.
-
Manage Stress: Stress can be a driver for hair shedding, so taking some time each day to focus on relieving any tension within your mind and body can make a difference. Breathing exercises and meditation are a nice and easy way to check in with yourself.
-
Brush Regularly: Brushing your hair regularly helps distribute the scalp's natural oils through the hair to keep it hydrated, helping avoid breakage.
-
Pair with Clear Protein+: Why stop at one source of protein? Pair Hair Protein with Clear Protein+ to bring even more protein (and hydration) to the table. Clear Protein+ adds 10g of grass-fed protein from collagen peptides + amino acids, plus electrolytes to support your fuel and hydration. More protein, more collagen, more hydration — consider this your hair health power couple.

FAQs
-
Can men and women take Hair Protein?
Yes. Hair Protein can be taken by both men and women. The formula isn’t hormone-specific; instead it supports fundamental aspects of hair health that are relevant to everyone, providing key nutrients and structural proteins that support healthy hair growth, strength, and quality.
-
Will Hair Protein work for all hair types and textures?
Yes. Hair Protein is designed to support healthy hair from within, regardless of hair type or texture. Because it works systemically rather than topically, its benefits aren’t specific to straight, wavy, curly, or coily hair- or dependent on a particular haircare routine. The formula provides nutrients, proteins, and botanicals that support healthy hair growth, strength, and quality across hair types.
-
How and when should I take Hair Protein?
Take one serving daily, with or without food, at whatever time works best for your routine. Mix with 8–12 oz of water, adjusting with more water if you prefer a lighter flavor. For the smoothest mix, dissolve the powder in room-temperature water first, then add ice.
Hair Protein has a light, natural-tasting lemonade flavor designed for easy daily use. Enjoy it on its own or mix it into other beverages like smoothies or juice. It also pairs well with Clear Protein+, so the two can be mixed together in one refreshing drink.
For best results, take Hair Protein consistently for at least 3 months, as hair grows gradually and follows a natural growth cycle. Continued daily use can help maintain ongoing nutritional support for healthy hair.
-
How long will it take to see results?
Some benefits can start showing up within the first month, but hair growth takes time. Lustriva® was clinically shown to increase hair thickness in as early as 3 weeks, while the pea sprout extract showed a reduction in hair loss after 1 month. We recommend consumers take Hair Protein consistently for at least 3 months for best results.
-
Can Hair Protein support postpartum hair changes?
While Hair Protein is not a hormonal formula and isn’t designed to correct the underlying hormonal changes of postpartum, it can support many of the factors that contribute to healthy hair during this transition. Stress, disrupted sleep, and increased nutritional demands during the postpartum period can all influence overall hair health. Hair Protein’s collagen and keratin protein, micronutrients, and clinically studied ingredients support the hair-growth cycle for strength, thickness, and decreased shedding support. KSM-66® ashwagandha also provides additional stress support. If you are pregnant or breastfeeding, we recommend checking with your doctor before starting Hair Protein.
-
Does Hair Protein support age-related changes in hair?
Yes. As we age, the hair growth cycle can shift- hair may spend less time in the active growth phase, while changes in follicle function and hair-fiber production can contribute to thinner, weaker, or slower-growing hair. This means that maintaining adequate protein and key nutrients becomes increasingly important with age. Hair Protein supports these foundational aspects of hair health with protein, nutrients, and clinically studied ingredients that support thicker hair, healthy growth, and follicle and scalp health. Because it isn’t designed around a specific hormonal pathway, it can support healthy hair throughout different stages of aging.
-
Does Hair Protein support PCOS-related hair loss?
While Hair Protein is not a hormonal formula and isn’t designed to address the underlying hormonal and metabolic factors associated with PCOS, it can support many of the factors that contribute to healthy hair.
Hair Protein’s collagen and keratin protein, micronutrients, and clinically studied ingredients support the hair-growth cycle for strength, thickness, and decreased shedding support, while KSM-66® ashwagandha provides additional stress support.
For more foundational PCOS support, we recommend pairing Hair Protein with Arrae Inositol. Its clinically studied 40:1 ratio of myo- and D-chiro-inositol is designed to support hormone signaling, healthy insulin function, and hormonal and metabolic balance while Hair Protein provides targeted support for healthier, stronger-looking hair.*
-
Will Hair Protein cause breakouts?
Hair Protein is not expected to cause breakouts. Our formula uses Lustriva®, a clinically studied and well tolerated biotin-containing complex that is not associated with breakouts, and includes vitamin B5 and zinc for added skin health support.
