Cruelty-Free Shampoo: Nature’s Gate and Kirk’s Natural

Cruelty Free Shampoo Cruelty Free Shampoo: Natures Gate and Kirks Natural

When it comes to shampoo, I’m not too picky. I just want it to clean my hair without totally stripping it of moisture. And, of course, I don’t want animals harmed in its production. Two products that fit (well, actually – exceed) the bill are Nature’s Gate Biotin Shampoo and Kirk’s Original Coco Castile Shampoo.

Nature’s Gate and Kirk’s Natural are Leaping Bunny-certified, PETA-approved, and vegan. Both of these shampoos are affordable, gentle, and effective.

Nature’s Gate feels like a typical shampoo. I don’t notice a difference from all the other shampoos out there. It does a great job cleaning my hair and doesn’t feel drying. It has a subtle minty smell.

Kirk’s feels especially gentle. It doesn’t lather as much as typical shampoos, so it feels a bit different than what you might be used to. I really like that it removes oil but, unlike with many shampoos, I don’t feel like I have to drench my hair in conditioner the second I rinse it out. It’s fragrance-free.

The Nature’s Gate Biotin shampoo says it’s for weak, thinning hair, but I tend to disregard claims like that. Biotin supplements may help your hair grow stronger in the future, but the hair on your head right now is already dead… so I’m skeptical of the idea that a shampoo can fortify it. Regardless, if you buy it for that purpose and it works for you, that’s great. I don’t necessarily recommend this formula over any of Nature’s Gate other shampoo formulas – I’ve tried others and they’ve all worked, as far as I can tell, completely the same. I just happen to be using this one at the moment and I also particularly like the scent.


Sodium Lauryl Sulfate Free

I know many people only buy sulfate-free hair care. As you can see from the labels, both of these products make sulfate-related claims. While I can’t personally offer any insights on those claims, here are the ingredients for reference. Just click the arrow for the full lists.

Nature’s Gate Biotin Shampoo Ingredients: Water, Cocamidopropyl Hydroxysultaine (Coconut Derived), Sodium Cocoyl Isethionate (Coconut), Disodium Cocoamphodiacetate (Coconut Derived), Lauryl Glucoside (Vegetable Derived), Glycerin (Vegetable), Biotin, Panthenol, Hydrolyzed Soy Protein, Hydrolyzed Vegetable Protein, Simmondsia Chinensis (Jojoba) Seed Oil, Borago Officinalis (Borage) Seed Oil, Tocopherol (Vitamin E), Ascorbic Acid (Vitamin C), Hordeum Vulgare (Barley) Extract, Geranium Maculatum Extract, Olea Europaea (Olive) Leaf Extract, Viola Tricolor (Pansy) Extract, Sodium Riboflavin Phosphate, Niacin, Sodium PCA, Sodium Lactate, Cysteine, Arginine, Serine, Threonine, Folic Acid, Aspartic Acid, Ascorbyl Palmitate (Vitamin C), PCA, Glycine, Alanine, Valine, Isoleucine, Proline, Histidine, Phenylalanine, Polysorbate 20 (vegetable derived), Leuconostoc/Radish Root Ferment Filtrate, Hydroxypropyl Methylcellulose (Plant Derived), Glyceryl Undecylenate (Vegetable Derived), Sodium Hydroxide, Phenoxyethanol, Citric Acid (Vegetable Derived), Fragrance

Kirk’s does have Ammonium Laureth Sulfate, so if you’re trying to avoid sulfates altogether, this probably isn’t the shampoo for you.

Overall, I don’t think you can go too far wrong with either product. If your hair is drier, you might want to check out Kirk’s and if you have oilier hair, you may opt for Nature’s Gate. But I think they’re both universal and could be used by any hair type.
