How Do You Make Natural Shampoo at Home? A Simple, Eco-Friendly Guide

Clean hair doesn’t have to come with chemicals. A DIY natural shampoo gives you shine and safety without stripping your scalp.

You can make a safe, eco-friendly shampoo at home using castile soap, aloe vera, and essential oils. With the right ingredients and a little care, you’ll protect both your hair and the planet.

You don’t need to spend $20 on organic shampoo to avoid sulfates¹ and parabens².

You can make your own in just minutes with a few ingredients from your kitchen or natural store. It’s safer, cheaper, and better for the environment too.

Why Make Natural Shampoo at Home?

Hair shouldn’t suffer from chemical overload. Many commercial shampoos contain sulfates, parabens, or artificial fragrances³ that can dry out the scalp, irritate sensitive skin, and damage dyed hair.

Making shampoo at home helps you skip harsh chemicals, reduce plastic use, and save up to $25 per bottle.

You can control what touches your hair. With a homemade mix, you get to pick only the ingredients that are gentle and effective. No mystery. No toxins. And it costs just around $1 per batch.

Choosing Safe and Effective Ingredients?

Ever read the label on your shampoo and seen words you can’t pronounce? Let’s fix that.

The safest ingredients for DIY shampoo include castile soap, aloe vera, essential oils, and natural thickeners⁴.

Best Natural Shampoo Ingredients

Ingredient	Purpose	Notes
Castile Soap	Main cleanser	pH ~9, needs ACV rinse to rebalance
Aloe Vera Gel	Soothes scalp	Hydrates, gentle on skin
Jojoba Oil	Moisturizer	Lightweight, close to natural sebum
Essential Oils	Scent + Scalp Health	Rosemary, lavender, tea tree
Arrowroot Powder	Thickener	Optional for better texture
Geogard 221	Natural preservative	Needed for shelf life beyond 7 days

Avoid harsh cleaners like baking soda⁵, bleach, or household detergents. These can throw off your hair’s pH and cause more harm than good.

Basic Natural Shampoo Recipe for All Hair Types?

Don’t know where to start? This recipe is gentle enough for most hair types and can be adjusted easily.

Mix ½ cup water, ¼ cup castile soap, 1 tsp jojoba oil, and 10 drops of essential oil for a simple, balanced shampoo.

Here’s how to do it:

Ingredients

• ½ cup distilled water
• ¼ cup liquid castile soap
• 1 tsp jojoba oil (or avocado oil for dry hair)
• 10 drops essential oil (lavender, rosemary, or tea tree)
• ½ tsp arrowroot powder (optional thickener)
• 0.5% Geogard 221 preservative (optional)

Instructions

1. Boil the water, then let it cool.
2. Add castile soap and stir gently.
3. Mix in jojoba oil and essential oils.
4. Add arrowroot to thicken, if desired.
5. Add preservative if you plan to store for more than 1 week.
6. Pour into a dark bottle with a pump top.
7. Shake before each use. Follow with 1 tbsp apple cider vinegar + 1 cup water rinse to restore pH⁶.

Customizing Shampoo for Specific Hair Needs?

Hair isn’t one-size-fits-all. Your curls need different care than oily roots.

Adjust your shampoo base with ingredients like aloe vera for dry scalps, or tea tree oil⁷ for oily ones.

Common Adjustments by Hair Type

• Oily Hair: Add 5 drops tea tree oil; skip extra oils. Use ACV rinse.
• Dry Hair: Add 2 tbsp aloe vera or coconut milk; use heavier oils like avocado.
• Curly/Afro Hair: Add rose water or hydrosol; stick with gentle cleansers like decyl glucoside.
• Color-Treated Hair: Avoid baking soda and stick to pH-balanced ingredients⁸ like shikakai powder.
• Sensitive Scalp: Use chamomile tea instead of water and lavender essential oil.

Safety and Storage Tips for Homemade Shampoo?

Homemade doesn’t mean careless. Mold and bacteria can grow fast in your bathroom.

Store your shampoo in an airless pump bottle⁹, add a preservative, and keep it cool and dry.

Key Tips

• Use Geogard 221 (0.5%) for batches stored more than 1 week.
• Always check pH with a strip—aim for 4–5.
• Refrigerate if not using preservative.
• Avoid metal containers—use glass or plastic.

Eco-Friendly Practices in Shampoo Making?

You want clean hair, not a dirty planet.

Choose biodegradable ingredients, reusable containers, and low-water recipes¹⁰ to reduce waste.

Ways to go green:

• Buy oils and soap in bulk.
• Use plant-based cleaners like castile or shikakai.
• Skip plastic bottles—reuse glass or aluminum pumps.
• Make small batches to avoid waste.

Common Mistakes to Avoid?

Small mistakes can leave you with bad hair days.

The biggest DIY shampoo mistakes include ignoring pH, forgetting preservatives, and using baking soda daily¹¹.

Avoid this list:

• No pH test: high pH dries and damages hair
• No preservative in a wet product: leads to mold
• Too much baking soda: strips oils and color
• Overmixing: creates foam, not better cleaning
• Leaving in humid bathroom: encourages bacteria

Benefits of Pairing with a Natural Conditioner?

Shampoo alone isn’t enough. Finish strong.

Use a vinegar or oil-based rinse¹² to seal the cuticle, soften strands, and balance pH.

Simple Conditioner Rinse

• 1 tbsp apple cider vinegar
• 1 cup water
• 1 tsp coconut or argan oil
• 5 drops lavender essential oil

Pour slowly through hair after shampoo. Rinse lightly or leave in depending on hair type.

Conclusion

Making natural shampoo at home is cheap, clean, and safe—if you balance pH, store it right, and use the right ingredients.
