Terms of Service
Last updated: August 3, 2026
Introduction
Welcome to HennaHand (“we,” “our,” or “us”). These Terms of Service (“Terms”) govern your use of our website at mahrosh.com and all associated calculators, guides, and services (collectively, the “Service”).
By accessing or using the Service, you agree to be bound by these Terms. If you disagree with any part of them, please do not use the Service.
Acceptance of Terms
By accessing, browsing, or using HennaHand, you acknowledge that you have read, understood, and agree to be bound by these Terms and our Privacy Policy, which is incorporated by reference.
We may update these Terms at any time. Your continued use of the Service after changes are posted constitutes acceptance of the revised Terms.
Craft Aids, Not Medical Advice — Verify Before You Rely
HennaHand’s calculators are craft and planning aids covering natural henna (Lawsonia inermis) only. They apply common mixing ratios and rules of thumb to the values you enter and round results for readability. Nothing on the Service is medical, dermatological, or professional advice of any kind, and the Service does not diagnose, treat, or offer guidance on any skin condition or health concern. Always patch-test a new batch or oil on a small area of skin before full application, and consult a doctor or dermatologist about any skin reaction or health question.
Description of Service
HennaHand provides free, browser-based calculators and educational resources, including:
- A henna paste consistency calculator
- A henna cone quantity calculator
- A henna stain time guide
- A mehndi pattern time estimator
- An essential oil ratio calculator
- A henna dry time calculator
- Guides, explainers, and reference content on henna and mehndi
All tools are provided free of charge. We may modify, suspend, or discontinue any part of the Service at any time.
Your Responsibilities
When using the Service, you agree to:
- Use the tools in good faith for learning, craft projects, or personal use
- Use only natural henna and never products marketed as “black henna”
- Patch-test new batches, oils, and blends before full application
- Not disrupt, overload, or attempt to compromise the website
- Respect intellectual property rights
You are responsible for exercising your own judgment and for consulting a medical professional about any skin reaction or health concern.
Accuracy and Disclaimers
While we aim for sound, widely-used craft ratios, we cannot guarantee that every calculation suits your specific powder, climate, or skin. Results are estimates based on common conventions and the figures you provide, and are rounded for display. HennaHand makes no warranties, express or implied, including implied warranties of merchantability, fitness for a particular purpose, or non-infringement.
Intellectual Property
All content on this website — text, graphics, logos, tools, calculators, and software — is the property of HennaHand or its content suppliers and is protected by applicable copyright and other laws. You may use the tools for personal and educational purposes; you may not copy, resell, or reverse engineer them, or remove proprietary notices.
Limitation of Liability
In no event shall HennaHand or its suppliers be liable for any damages (including, without limitation, a spoiled batch, a design that didn’t stain as expected, or other losses) arising out of your use of, or inability to use, the Service, even if we have been advised of the possibility of such damages.
Third-Party Links and Ads
The Service may link to third-party websites and displays third-party advertisements. We do not control and are not responsible for their content, and inclusion of a link or ad is not an endorsement. Your use of any third-party site is at your own risk.
Governing Law
These Terms are governed by and construed in accordance with the laws of the United States, and you submit to the exclusive jurisdiction of the courts located there.
