PPD-free color with a 90-day money-back guarantee
By HELA HAIR
Covering your grays should fit into your day. With HELA HAIR, you can refresh your color at home using a brush application and a PPD-free formula. Add published skin-compatibility testing and a 90-day money-back guarantee, and you have clear reasons to make HELA part of your routine.
Whether you are touching up visible roots or choosing your next shade, start with what matters to you: the ingredients, the application, and the support available after your order.

Color with a PPD-free formula
HELA uses Toluene Diamine Sulfate, commonly called TDS, instead of PPD. If avoiding PPD is one of your priorities when shopping for hair color, this is a useful place to start. Our ingredient information lets you look beyond the shade name and understand more about the product you are choosing.
PPD-free does not mean allergy-free. TDS and other hair-color ingredients can still cause reactions. Follow the product’s allergy-test instructions before every use. If you have previously reacted to hair dye, consult a dermatologist before choosing another oxidative dye, including HELA.

Skin compatibility testing with published results
We want customers to understand what stands behind our testing claim. HELA publishes a summary of a dermatologist-supervised Human Repeat Insult Patch Test, or HRIPT, involving 106 participants. Half described their skin as sensitive. No clinically significant irritation or evidence of sensitisation was observed in the study panel.
The study covered HELA’s Black shade under controlled conditions. It does not guarantee that nobody will react, apply automatically to every shade, or measure gray coverage and color longevity. It gives you specific information to consider when choosing your color product.
