DIY Rosemary Water for Hair Growth 🌿

Let’s talk about something we don’t discuss enough as vegans — hair health.

When I transitioned to a fully plant-based lifestyle, my skin glowed, digestion improved, and I felt fantastic. However, a few months in, I noticed more hair in the shower drain than I was used to. Naturally, I panicked a little.

It turns out this is actually pretty common among new vegans. Our bodies undergo a transition phase as they adjust to a new nutrient profile. This shift can sometimes manifest as temporary hair thinning or shedding. If you’ve experienced this too, you are NOT alone. There’s so much we can do to support our hair naturally while getting our nutrition right.

If you're looking for a deeper dive on this topic, I wrote a full post all about *hair loss and hair health for new vegans. It covers essential nutrients, supplements, and plant-based tips for supporting your hair from the inside out. If you feel like your diet has affected your hair health, be sure to check it out!

Homemade Remedies for Hair Growth

One of the best (and easiest) natural hair growth remedies I’ve discovered is homemade rosemary water. It’s completely vegan, clean, and made with just a few ingredients you might already have. Let me tell you… this stuff is magic for your scalp.

Why Rosemary Works for Hair Growth

Rosemary isn’t just a fragrant herb for cooking; it has been used for centuries in natural medicine for its ability to:

• Stimulate circulation to the scalp, promoting new hair growth

• Strengthen hair follicles

• Help reduce shedding and breakage

• Soothe irritated, itchy scalps

• Even assist with dandruff and dryness

  
  

One active compound, carnosic acid, has been shown to repair nerve damage and improve blood flow to the scalp. This is crucial for hair regrowth. I like to think of rosemary as a gentle yet powerful wake-up call for sleepy hair follicles.

How Much Rosemary to Use

For a single batch, you need:

• 2–3 sprigs of fresh rosemary, about 4–6 inches long

• Or 2 tablespoons of dried rosemary, equally effective!

  
  

Don’t stress about exact measurements; herbal infusions are flexible. Just avoid using wilted or slimy sprigs. Look for vibrant, fragrant greens.

Rosemary Water Recipe for Hair Growth 🌿

Prep time: 5 minutes

Cook time: 15 minutes (boil + steep)

Yield: About 12 oz (fills one standard spray bottle)

Shelf life: 7–10 days refrigerated

• 

• 

• 

Ingredients:

• 2–3 fresh rosemary sprigs (or 2 tablespoons dried rosemary)

• 2 cups filtered water

• Optional: 1–2 drops rosemary essential oil

• Optional: 1 tsp apple cider vinegar (for pH balancing and extra scalp support)

  
  

Instructions:

1. Boil the water. In a small pot, bring 2 cups of filtered water to a gentle boil.

2. Add the rosemary. Remove from heat, add the rosemary sprigs, and cover with a lid.

3. Steep. Let it steep for 10–15 minutes until the water turns a light amber color and smells heavenly. This allows the rosemary to infuse its beneficial oils into the water.

4. Strain. Remove the rosemary sprigs and let the mixture cool completely.

5. Optional boosters. Add optional ingredients like 1–2 drops of rosemary essential oil and/or 1 tsp apple cider vinegar to enhance benefits. Stir well.

6. Bottle it up. Pour into your spray bottle(s). Store in the fridge, using it within 7–10 days. You can also freeze extras in ice cube trays!

How Much Should You Spray? (And Where?)

When applying your rosemary hair growth spray, here’s my routine:

• Use 8–10 sprays directly onto your scalp, avoiding the lengths of your hair.

• Focus on thinner or delicate areas, such as around the temples, forehead, and crown.

• Part your hair in a few spots to access your scalp and gently massage it in with your fingertips.

  
  

I prefer to use this spray before bed so it can work overnight — no rinse needed!

The Best Spray Bottles to Use

I recommend using glass spray bottles due to several advantages:

• Glass won’t leach chemicals into your herbal mixture, especially with essential oils.

• It’s more eco-friendly and reusable.

• It holds up better in the fridge or freezer.

• Amber or *cobalt blue glass protects the infusion from light, keeping it fresh longer.

  
  

If you only have a clean plastic spray bottle, that’s perfectly fine — just ensure it’s BPA-free and hasn’t been used for cleaning products.

Here are my favorite picks:

• 16 oz amber glass spray bottle for your main batch.

• 4 oz travel-size bottles for sharing or keeping in your gym bag.

• Bottle Size + Scaling for Gifts.

  
  

The recipe makes about 12 oz of rosemary spray, fitting perfectly in a standard 12 oz glass spray bottle. If you don’t have a 12 oz bottle, you can split it between two 6 oz bottles or three 4 oz bottles.

Want to make a larger batch to gift friends or family?

You can double the recipe using:

• 4 cups of filtered water

• 4–6 rosemary sprigs (or 4 tablespoons dried rosemary)

  
  

This yields roughly 24 oz of rosemary spray, enough for six 4 oz mini glass bottles or to reuse empty bottles around your home. They make cute gifts!

Why Add Rosemary Essential Oil

You’ll see it mentioned as an optional ingredient in the recipe, and here’s why: rosemary essential oil is potent. A massive amount of rosemary leaves — like pounds of plant material — is needed to create just one small bottle of essential oil. Consequently, it’s packed with concentrated plant compounds.

If you decide to include essential oil, make sure to use a 100% pure, therapeutic-grade rosemary essential oil (ideally steam-distilled and from a reputable brand). Avoid oils labeled “fragrance” or “perfume” as they may contain synthetic additives harmful to your scalp. Always dilute properly — I recommend just 1–2 drops per batch of this spray.

FAQs About Rosemary Hair Growth

Q: Can I use rosemary that has turned brown?

If only a few leaves are brown, pick them off and use the healthy green sprigs. If most of the sprig looks wilted or discolored, it's best to compost it and use fresher rosemary for optimal results.

Q: Do I need filtered water?

I highly recommend it! Even if NYC tap water is good, filtered water is gentler on your hair and helps prolong your spray's shelf life.

Q: What’s the purpose of adding rosemary essential oil?

The essential oil offers a concentrated boost of the fresh herb's benefits. It promotes blood flow to the scalp and encourages new growth. However, it’s very strong, so use it with caution. I keep it optional for those with sensitive skin.

Q: Can I use this every day?

You can, but I usually stick to 2–3 times a week to avoid overwhelming my scalp. Think of it as watering a plant — more isn't always better!

Q: What if I see no change?

Hair growth takes time, especially if linked to nutritional shifts or stress. Stick with it for at least 4–6 weeks. In the meantime, ensure you’re eating a range of plant-based proteins, B vitamins, omega-3s, and iron-rich foods — all crucial for healthy hair.

Q: Could age or genetics play a role?

Absolutely. I never want to place all the blame on diet alone. Hair thinning can be a natural aging process, especially for women. Factors like hormonal changes, genetics, stress, and age all influence hair appearance and health. That's why it's essential to care for your body from both the inside and the outside.

Q: Can I use dried rosemary instead of fresh?

Yes! Use 2 tablespoons of dried rosemary and follow the same steps. It’s equally effective and often more convenient.

Q: How should I store it?

Keep it in the fridge in a glass spray bottle if possible. Use within 7–10 days, or freeze leftovers to extend freshness.
