10 Best Natural Ingredients for Hair Growth (Backed by Science!)
If your shower drain looks like it’s auditioning for a horror movie, or your ponytail is suddenly giving off "stringy spaghetti vibes," you’re not alone. Hair thinning, slow growth, or even the dreaded shedding season (why does it always happen at the worst times?) can make anyone desperate for a solution.
Good news: Nature’s got your back. There are actual science-backed ingredients that can help support healthier, fuller, and longer hair. No magic potions, just real, natural goodness that your hair will love. Let’s get into it!
1. ROSEMARY OIL
Rosemary oil is basically the overachiever of the essential oil world. Research shows that it works as effectively as minoxidil (a common hair growth treatment) in promoting hair regrowth, minus the scalp irritation. Just mix a few drops with a carrier oil (like coconut oil) and massage it into your scalp a few times a week."
Imagine—Watching new baby hairs pop up along your hairline can bring back confidence and make you feel like you’re in control of your hair health again.
Helpful Resource: Look for high-quality, organic rosemary oil like this one for the best results.
2. COLLAGEN
Your hair is made up of keratin, and guess what helps your body produce keratin? Yep, collagen. Specifically, marine collagen peptides—like those in this Collagen Elixir—help strengthen hair, improve elasticity, and even give you that I woke up like this shine. Bonus: Your skin and nails will thank you too.
Feeling great about your hair also means feeling great about your overall appearance. Strong, shiny hair can make you feel more polished and put together, boosting your self-esteem.

3. CASTOR OIL
Castor oil has been around forever, and for good reason. It’s packed with ricinoleic acid, which helps improve blood circulation to the scalp and nourish hair follicles. Just a small amount goes a long way—unless you want to spend an hour trying to wash it out (lesson learned).
Plus, the process of massaging castor oil into your scalp can be a self-care ritual that helps you unwind while also giving your hair the TLC it deserves.
Helpful Resource: Try this organic cold-pressed castor oil for maximum benefits.
4. BIOTIN
Ah, biotin—the ingredient you’ve probably seen on every hair vitamin bottle. It helps strengthen hair and reduces breakage, making it essential for anyone trying to grow out their strands. You can get it through food (eggs, nuts, salmon) or supplements.
Added bonus—Stronger hair means fewer bad hair days, which can be a serious mood booster!

5. ALOE VERA
This little miracle plant does wonders for your scalp by reducing inflammation and promoting a healthy environment for hair to grow. Try using fresh aloe vera gel as a scalp mask or look for shampoos that include it as a key ingredient. A calm, itch-free scalp leads to a more comfortable and confident you…who wouldn’t want that?!
Helpful Resource: This organic aloe vera gel is perfect for scalp treatments.
6. PEPPERMINT OIL
Not just for fresh breath! Studies show peppermint oil can help with hair growth by increasing circulation to the scalp. Plus, it gives that refreshing tingly feeling (aka proof it’s working, right?). Mix it with a carrier oil and massage it into your scalp.
The cooling sensation of peppermint oil can be incredibly refreshing, making hair care feel like a luxurious spa experience.
Helpful Resource: Try this pure peppermint oil for an invigorating scalp massage.
7. GINSENG
Ginseng isn’t just for energy; it helps strengthen hair follicles and may even promote regrowth. Look for shampoos or treatments with ginseng extract to give your hair an extra boost.
And—a healthier scalp and stronger hair can make styling easier and more enjoyable.

Reducing hair loss can bring a major sense of relief and confidence—wouldn’t you agree?!
Helpful Resource: This high-quality saw palmetto supplement is a great option.

Hair is made up of protein, so if your diet is lacking in this department, your strands will feel it. High-quality, super absorbable Tri-Release Protein or IsaLean Protein Shake provide essential amino acids to support hair growth and strength.
