Shihuanuo Hair Color Shampoo and Dye Guide: Uses, Safety, and Results
Shihuanuo is a hair color brand and manufacturer from Guangdong, China, widely recognized for its color depositing shampoos and traditional developer based dyes. It operates as both a consumer facing brand and a supplier for other companies, producing private label formulas as well as selling under its own name. In simple words, Shihuanuo makes affordable at home coloring solutions, especially three in one shampoos that cleanse, color, and condition in one step.
This guide explains everything about Shihuanuo, including its background, how its products work, how safe they are, who they are best suited for, and how to choose wisely.
Understanding Shihuanuo
Shihuanuo Guangdong Biotechnology presents itself as a professional hair color producer with large manufacturing facilities and SGS certification. The company emphasizes its research and development work and also mentions collaboration with the Guangdong Provincial Institute of Traditional Chinese Medicine, which helps market its use of herbal and natural extracts.
On major marketplaces such as Amazon and Walmart, Shihuanuo products are promoted as quick gray coverage solutions. The brand highlights convenience, herbal extracts, and ammonia free claims. Because the company functions as both a supplier and a retail brand, buyers may see Shihuanuo items under its own name or private label equivalents.
Shihuanuo product range
Hair Dye Shampoo
The three in one hair dye shampoo is the brand’s signature product. It deposits color while washing and conditioning, making the process easy for home use. Common shades include black, dark brown, chestnut, coffee, and wine red.
Many listings mention herbal extracts such as camellia, ginseng, macadamia, and ganoderma. While these extracts sound appealing, they are often more of a marketing feature than a proven benefit, so the real performance depends on the full formula.
Results are often advertised to last three to four weeks, but in reality, longevity depends on hair type. Porous or pre lightened hair tends to hold color longer, while resistant gray hair may require repeated use to achieve noticeable blending.
Hair Color Cream and Developer
For people looking for stronger gray coverage or longer lasting color changes, Shihuanuo produces traditional color creams with developer. These are oxidative dyes, which work by opening the cuticle, allowing color molecules to enter, and then locking them inside the hair fiber. They usually last longer and provide deeper results than shampoos.
Bleach Powder and Accessories
The company also produces bleach powder and related items. These are used for lifting hair several levels lighter, often before applying a new color. They are generally intended for dramatic transformations, for example taking dark hair to a lighter or brighter shade.
How Shihuanuo Dye Shampoo Works?
Color shampoos belong to the category of color depositing products. They typically use two different methods:
- Direct dye shampoos place color on the surface of the hair strand. They are easy to apply and give instant results, but the shade usually washes out more quickly.
- Oxidative dye shampoos use alkalizers and mild oxidation to form color molecules inside the hair strand. They generally last longer but involve stronger chemicals.
- Studies comparing both approaches show that coating systems give an immediate tone boost, while oxidation systems offer longer color retention and can help hair maintain moisture better.
The Shihuanuo shampoo line appears to focus mainly on deposit and coating technology, promoting it as quick and convenient.
Ammonia Free Claims Explained
Many Shihuanuo products highlight that they are ammonia free. While this is true, it does not mean they are free of all strong chemicals. Instead of ammonia, these formulas often use monoethanolamine (MEA) or similar substitutes.
MEA raises the hair’s pH so color can enter, but it does not lighten as strongly as ammonia. If overused, it can still cause scalp irritation or dryness. So ammonia free does not mean risk free, and reading the ingredient list is always important.
Safety, Allergens, and Dermatologist Advice
Hair dyes, including shampoos, can cause allergic reactions or irritation. The most well known allergen in permanent dyes is p-phenylenediamine (PPD). Dermatologists warn that PPD can cause reactions ranging from mild itching to severe swelling.
Because of this, professionals strongly recommend patch testing before every use, even with brands you have used before. Shihuanuo products are no exception.
The US Food and Drug Administration (FDA) gives clear consumer advice: follow the label exactly, wear gloves, avoid eye contact, rinse thoroughly, and never leave the product on longer than directed.
In Europe, the Scientific Committee on Consumer Safety (SCCS) sets limits for PPD and other dye chemicals. Some are restricted or banned altogether, depending on safety reviews.
What to Expect from Shihuanuo Products?
Shihuanuo hair dye shampoo should be seen as a refreshing and blending product, not a full permanent dye. It can soften the look of grays and revive faded tones, but very resistant gray hair may only show partial coverage.
Results depend on your hair. Virgin dark hair may show subtle results, while bleached or porous hair absorbs color more easily and can hold it longer. If you wash daily, you may need to reapply weekly. If you wash less often, you can stretch the color closer to a month.
For major changes, such as lightening hair several levels or shifting to a bold cool tone, Shihuanuo’s developer based creams or bleach powder are better choices.
Who Shihuanuo Suits Best?
Shihuanuo shampoos are ideal for people who want a quick and easy way to refresh tone or blend gray without spending much. They are also useful for maintaining color between salon visits, keeping hair looking fresh without the cost or time of a professional service.
However, if you have a history of dye allergies or sensitive skin, you should proceed carefully. Always check the ingredients and consult with a dermatologist if you are unsure. Even ammonia free shampoos can irritate because of dyes, preservatives, or fragrances.
How to Choose the Right Shihuanuo Product?
Choosing the right Shihuanuo product depends on your goals. If you want fast maintenance and gray blending, start with the shampoo. If you want a permanent change, use the cream with developer.
When picking a shade, first match the depth (light, medium, or dark) and then adjust the tone (warm or cool). If you are unsure, go slightly lighter because repeated use can darken the result.
Always read the label carefully. Look for dye type, alkalizer, and potential irritants. Ammonia free does not equal irritation free.
Finally, set realistic expectations. Claims of three to four weeks of vivid color may be true for some, but your results depend on your unique hair and habits.
Applying Shihuanuo Shampoo at Home?
For best results, follow these steps:
- Do a small skin test on your arm or behind your ear at least 48 hours before applying the product to check for any reaction. Wear gloves and apply to damp hair in sections for even coverage.
- Massage it in like a normal shampoo, then stop and let it sit for the time suggested. Begin with the shorter end of the range until you see how your hair reacts.
- Rinse until the water runs clear, condition if the directions say so, then dry and check your results in natural light. Adjust timing in future applications as needed.
This process makes Shihuanuo shampoo simple even for beginners, though patience and practice help in learning how your hair responds.
Availability and Sourcing
Shihuanuo products are widely sold on Amazon, Walmart, and other online marketplaces. The brand also runs B2B supplier pages for private label clients. Since multiple sellers may list the same item, always compare shade names, bottle sizes, return policies, and ingredient lists before purchasing.
For salons or resellers, Shihuanuo offers OEM and ODM services, producing private label color products. Business buyers should request certificates, compliance documents, and updated test data before placing orders.
Conclusion
Shihuanuo is both a manufacturer and a brand that delivers affordable and accessible hair coloring products. Its shampoo is simple, fast, and practical for blending grays or refreshing tone. Shihuanuo’s cream with developer provides more intense coverage and durability compared to quick color shampoos.
The brand’s real strength is convenience and price, making at home coloring easier for many people. Safe use requires reading labels, patch testing, and keeping expectations realistic.
When used thoughtfully, Shihuanuo can be a helpful part of your hair care routine, giving you the confidence of refreshed color without the stress and expense of frequent salon visits.
Frequently Asked Questions (FAQs)
Is Shihuanuo permanent or semi permanent?
Most shampoos are semi permanent, meaning they fade with washing. The cream and developer products are permanent.
Can I use it if I am allergic to hair dye?
If you have had an allergic reaction before, consult a doctor first. Shihuanuo products, like all dyes, may contain PPD or related chemicals that can trigger reactions.
Why do ammonia free products still irritate?
They usually contain MEA or other strong chemicals. Dyes, fragrance, and preservatives can also irritate sensitive skin.
Are color shampoos as strong as salon dyes?
No. They are designed for convenience and blending, not for deep permanent changes. Salon oxidative dyes last longer and cover resistant gray more fully.
