What I Loved:

What really stood out to me was how this oil doesn’t just sit on top of your hair-it actually absorbs nicely to deliver deep nourishment without that heavy, greasy feeling. I’ve tried countless oils that promised growth but left my relaxed strands looking limp and oily; this one strikes the perfect balance. The tingling sensation from the mint and peppermint oil feels incredibly refreshing on the scalp, almost like a mini spa treatment that I look forward to. And let’s talk results: after a few weeks of consistent use, I noticed fewer broken hairs on my brush and a visible improvement in overall thickness. It’s rare to find a product that works this well without any fuss.

The Not-So-Great:

While most users love it, a handful find it can make their hair feel greasy if over-applied, so a little goes a long way.

Bottom Line:

If you’re looking for a multi-tasking oil that truly nourishes the scalp and strengthens relaxed hair without weighing it down, this is your winner.

Sometimes simplicity is key, and this oil proves it. The 100% pure formulation means you’re getting the unadulterated benefits of castor oil-known for its ricinoleic acid-and rosemary without any filler ingredients. I appreciate that it’s hexane-free and comes in a practical bottle. For relaxed hair, it’s a fantastic pre-shampoo treatment or overnight scalp oil that helps lock in moisture and soothe dryness.

This is a classic for a reason. It’s a lightweight, non-greasy dressing that you can apply directly to your scalp or hair, and it creates an ideal environment for growth without clogging pores. The coconut oil and vitamin E provide a hit of moisture that relaxed hair craves, helping to combat that persistent dryness.

What I Loved:

The ingredient list here is a powerhouse for relaxed hair. The combination of rosemary, castor, and biotin targets growth stimulation and strength from multiple angles. What impressed me most was the claim of being ‘non-greasy’-and it actually holds up. It absorbs relatively well for an oil blend, leaving hair with a silky, shiny finish rather than an oily one. Users with dry, brittle hair from conditions like alopecia have noted significant moisturizing benefits. It’s a thoughtful formula that feels luxurious and seems to understand the need for effective yet manageable hair oils.

The Not-So-Great:

As a newer blend, the long-term growth results are still being established compared to some more veteran products.

What I Loved:

The story behind this brand-created to help regrow hair after a misdiagnosis-adds a layer of genuine care that resonates. The oil has a refreshing, tingly sensation from the mint that feels like it’s actively working. It’s designed to be a ‘stimulator,’ and it lives up to that name. I found it to be quite soothing on an itchy, dry scalp, which is common with relaxed hair. Users who stick with it report seeing new growth, particularly around edges and bald spots, and appreciate that it’s not overly oily, leaving hair soft and manageable.

The Not-So-Great:

For those who believe in supporting hair growth from the inside out, this is a solid option. The high-potency biotin combined with collagen and bamboo extract targets hair strength and nail health simultaneously. Users report that their hair becomes noticeably thicker and shinier after a couple of months, and the capsules are easy to swallow. For relaxed hair, which can be nutrient-depleted from processing, a supplement like this can help fill nutritional gaps. It’s a cleaner, more straightforward formula than some of the ultra-premium supplements, which is appealing.

The Not-So-Great:

As with many internal supplements, some users experience mild stomach upset or nausea, especially when taken without food.

Bottom Line:

A straightforward internal supplement that can help fortify relaxed hair from within by addressing potential nutritional deficiencies.

What I Loved:

This product fills a very specific and often overlooked niche: hair growth support during and after menopause. Hormonal changes can hit relaxed hair hard, making it thinner and more brittle. This formula is specifically engineered to counteract those shifts. The clinical study showing improved growth for users is compelling. For women in this age group with relaxed hair, it offers a targeted solution that general products might miss, helping to restore a sense of thickness and scalp coverage.

The Not-So-Great:

It’s the most premium-priced option here, and the 4-capsule daily dose can be daunting, with common reports of stomach issues like constipation.

Bottom Line:

A highly specialized, dermatologist-recommended supplement for women over 45 to combat hormonal hair thinning, which can be a concern for maintaining relaxed hair.

Our Testing Process: Why These Rankings Are Different

Let’s be honest-most “best of” lists feel like they just copy Amazon’s top sellers. We wanted to do better. So, we started with a deep dive into 10 leading hair growth products specifically evaluated for their performance on relaxed hair. We didn’t just glance at star ratings; we analyzed thousands of user experiences, technical specs, and real-world feedback to see what actually works for chemically treated strands.

Our unique scoring system is 70% based on real-world performance-how effectively a product strengthens, moisturizes, and reduces breakage for relaxed hair-and 30% on innovation and competitive edge, like unique ingredient blends (think biotin-infused oils) or added tools (like scalp massagers). For example, our top pick, Mielle Organics Rosemary & Mint Hair Oil, scored an exceptional 9.5 for its award-winning, multi-tasking formula. Meanwhile, the Cantu Grow Strong Treatment, our Budget Pick, earned a 9.2 by delivering outstanding moisture and strength at a budget-friendly price point.

We compared everything from premium supplements to affordable oils, focusing on the performance-cost trade-offs. A score of 9.0 to 10.0 means “Exceptional” or “Excellent”-products that genuinely deliver on their promises for relaxed hair without empty hype. Our goal? To give you clear, data-driven insights you can trust, so you can find the right product for your unique hair journey.

Complete Buyer's Guide: How to Choose Hair Growth Products for Relaxed Hair

1. Start with Scalp Health

Relaxed hair has been through a chemical process that can compromise your scalp’s natural barrier. A healthy scalp is the non-negotiable foundation for growth. Look for products that soothe, nourish, and stimulate the scalp without causing buildup or irritation. Oils with ingredients like rosemary, peppermint, or tea tree oil are excellent for this, as they can improve circulation and calm inflammation.

2. Prioritize Strengthening and Moisture

Chemically relaxed strands are inherently more fragile and prone to breakage-the arch-nemesis of length retention. Your primary goal should be to fortify and hydrate. Seek out key ingredients like biotin, keratin, shea butter, and fatty acid-rich oils (castor, coconut, jojoba). These work to rebuild the hair’s internal structure and lock in moisture, making each strand more resilient against daily styling stress.

3. Decide: Topical Treatment vs. Internal Supplement

These work directly on the hair and scalp. They’re great for targeted issues like dry scalp, split ends, or immediate strengthening. They’re often more affordable and show results faster in terms of feel and appearance.

Internal Supplements (Vitamins, Capsules)

These address hair health from within by filling nutritional gaps. They can be powerful for long-term, overall improvement in thickness and growth rate, especially if your diet is lacking. However, they are a bigger investment and results take 3-6 months. A combined approach often works best for relaxed hair.

4. Understand Key Ingredients for Relaxed Hair

Biotin & Keratin: Building blocks for stronger hair strands, reducing breakage.
Rosemary Oil: Stimulates scalp circulation, linked to promoting growth.
Castor Oil: A humectant that draws moisture into the hair, rich in ricinoleic acid for nourishment.
Shea Butter & Coconut Oil: Superb emollients that seal moisture into dry, porous relaxed hair.
Vitamin E: An antioxidant that protects hair from environmental damage and supports a healthy scalp.

5. Incorporate Products into a Consistent Routine

Growth doesn’t happen overnight. Consistency is your most powerful tool. Integrate your chosen product into a simple, gentle routine. For oils, this might mean a pre-shampoo treatment 1-2 times a week. For creams, a mid-week moisturizing session. For supplements, taking them daily with a meal. Listen to your hair-if it feels weighed down, use less. If it’s still dry, apply more frequently. Patience and routine will yield the best results.

Frequently Asked Questions

1. Can hair growth products actually work on chemically relaxed hair?

Absolutely, but with a crucial caveat: they must focus on strengthening and preventing breakage as much as stimulating new growth. Relaxed hair is more vulnerable, so the right product will nourish the scalp to create a healthy environment and fortify the existing hair shaft so it can retain length. It’s a two-pronged approach-growth and retention-that delivers visible results.

2. How long will it take to see real results?

Manage your expectations realistically. For topical treatments like oils and creams, you might notice improved softness, shine, and reduced breakage within a few weeks. For visible new growth and increased thickness, it typically takes 2-3 months of consistent use. Internal supplements generally require a longer commitment of 3-6 months to see significant changes, as they work from within your body’s system.

3. Are hair growth supplements safe to use with relaxed hair?

In general, yes, but always consult your doctor before starting any new supplement, especially if you have underlying health conditions or take other medications. Supplements like Nutrafol or Primal Harvest are designed to support overall hair health, which can benefit relaxed hair. However, be aware that some may cause side effects like mild stomach upset. They are a complement to, not a replacement for, a good topical hair care routine.

4. Will these oils make my relaxed hair greasy or weigh it down?

They don’t have to! The key is application technique and choosing the right formula. Lightweight, non-greasy oils (like those with grapeseed or jojoba bases) are less likely to cause buildup. Always apply sparingly-focus on the scalp and ends-and avoid the mid-shafts if your hair is fine. Using oils as a pre-shampoo treatment that you wash out is also a great way to get the benefits without any residue.

Final Verdict

Navigating hair growth with relaxed hair is a journey of patience and choosing the right allies. Whether you’re drawn to the scalp-tingling boost of a nourishing oil like Mielle Organics, the straightforward moisture of a budget-friendly cream like Cantu, or the internal support of a targeted supplement, the most important step is to start. Consistency with a product that addresses both strength and scalp health will transform your results. Remember, your hair’s potential is waiting-it just needs the right support to show itself.
