Key Takeaways

• Color-treated hair is more vulnerable to thinning and breakage because chemical processing weakens the hair shaft, making a gentle, color-safe growth serum essential.
• When choosing a hair growth serum for colored hair, prioritize formulas free of sulfates, parabens, silicones, and harsh chemicals that can strip or dull your color.
  
• All three serums on this list are formulated without sulfates and harsh chemicals, but only Trybello offers a 120-day results guarantee, giving color-treated hair the extended trial window it needs.
• The Trybello Hair Helper Spray combines Biotin, Caffeine Extract, Organic Castor Oil, and Rice Water Extract in a lightweight, leave-in formula free from hormones, silicones, and parabens.

The Best Hair Growth Serums That Won't Fade Your Color

Chemical coloring opens the hair cuticle to deposit pigment, leaving strands more porous, drier, and structurally weaker than untreated hair. Over time, repeated coloring can lead to noticeable thinning, increased shedding, and breakage, especially around the hairline and crown.

The problem is that many conventional growth products contain sulfates, silicones, or alcohol-heavy formulas that accelerate color fading while doing little to address the root cause of thinning. The right serum needs to do two things at once: support the scalp and follicle environment for stronger regrowth while being gentle enough to preserve your color investment.

That means looking for plant-based, sulfate-free, and hormone-free formulas with ingredients that nourish the follicle without stripping or coating the hair shaft with harsh residues. The three serums below each take a different approach, but all are formulated with clean, color-safe ingredients designed to support growth without compromising your color.

Top 3 Hair Growth Serums for Color-Treated Hair

1. Trybello Hair Helper Spray

Our Trybello Hair Helper Spray is a non-oily treatment formulated to reduce shedding and support fuller-looking hair, without compromising your color.

Our Trybello Hair Helper Spray is a non-oily, leave-in treatment designed for women dealing with thinning, shedding, or weakened hair who want a clean, effective solution that fits seamlessly into any routine, including color-treated regimens. Rather than masking thinning with volumizing agents, our formula delivers targeted nourishment directly to the scalp, where it matters most.

The lightweight spray ensures even distribution without dripping or pooling, making daily application easier. The formula is vegan, cruelty-free, and free of hormones, sulfates, silicones, parabens, and harsh chemicals, so it strengthens and revitalizes your strands without interfering with your color.

Key Ingredients

Our formula combines targeted active ingredients that work together to support the hair growth cycle:

• Biotin (Vitamin B7) promotes keratin production, strengthening follicles from the inside out.
• Caffeine Extract supports blood circulation to the scalp and helps extend the anagen (growth) phase, while also naturally helping counteract the effects of DHT.
• Organic Castor Oil, rich in ricinoleic acid, provides deep scalp moisturization while helping maintain a healthy environment for growth.
  
• Rice Water Extract (Oryza Sativa) delivers amino acids and inositol that help strengthen hair from within and reduce shedding.
  

The formula also includes supporting botanicals such as Ginger Extract to invigorate the scalp and support circulation, plus Sophora Flavescens and Angelica Root extracts drawn from traditional Eastern hair care practices.

Expected Results & Timeline

With consistent daily use, our Trybello Hair Helper Spray is designed to deliver visible improvement in 16 weeks. In the first few weeks, many customers notice reduced shedding. By week 4, you may see less hair in the shower drain and on your hairbrush.

Around week 8–10, improved thickness and fullness typically become noticeable. By week 16, customers commonly report visibly longer, fuller, and healthier-looking hair.

Price: Our Trybello Hair Helper Spray starts at $49.97 per bottle. Multi-bottle bundles offer additional savings.

Vegamour GRO Hair Serum is a plant-based scalp serum that uses what the brand calls vegan phytoactives to help support the appearance of hair density and reduce signs of shedding. The water-based formula is cruelty-free and formulated without parabens, sulfates, phthalates, or mineral oils, making it a consideration for those with color-treated hair.

Key Ingredients

Vegamour's formula centers on Red Clover (Trifolium Pratense) and Mung Bean Sprout extracts as its primary phytoactives. Red clover is a source of isoflavones that may help support the hair follicle's growth cycle. The serum also includes Caffeine, Turmeric Callus Conditioned Media, Biotin, and plant-derived peptides.

Expected Results & Timeline

According to Vegamour, most users see results within 3–4 months of consistent daily use. The brand also notes that results may gradually reverse if you stop using the product.

Price: Vegamour GRO Hair Serum costs $64 for a 30 mL bottle (a 30-day supply).

Nutrafol Hair Serum is a physician-formulated topical serum that the brand positions as a complement to their oral Hair Growth Nutraceuticals.

The serum is clinically tested, color- and extension-safe, drug-free, and vegan. It is applied once daily directly to the scalp via a dropper. It is formulated without parabens, phthalates, gluten, silicones, sulfates, and synthetic fragrance, making it compatible with color-treated hair.

Key Ingredients

Nutrafol's serum is built around what the brand calls patent-pending Ashwagandha Exosomes, plant exosome-like nanovesicles from the Ashwagandha seed that can support cellular renewal.

The formula also features Irish Moss Peptides, Pea Sprout Extract, Sea Buckthorn, Moringa, Maca, Panax Ginseng Root Extract, along with Niacinamide and Panthenol for scalp hydration support.

Expected Results & Timeline

Nutrafol states that with daily use, users can expect to see visible improvements in hair thickness, strength, and reduced breakage in as little as 90 days. One bottle typically lasts 1–3 months, depending on whether the serum is applied to the entire scalp or only targeted areas.

Price: Nutrafol Hair Serum costs $49 for a single 1.7 oz bottle.
