Relaxing tight, coily curls without sacrificing hair health is a precise chemistry problem. The wrong formula causes scalp irritation or over-processed breakage, while the right one delivers smooth, manageable strands that last weeks. For anyone with naturally curly or coily hair, the choice between lye and no-lye formulas, the strength level, and the conditioning ingredients determines whether the experience is transformative or damaging.
I’m Mohammad — the founder and writer behind ProteinJug. Over the last 15 years, I’ve analyzed hundreds of hair care chemistry profiles, comparing alkaline content, moisturizing agents, and pH-balancing ingredients to separate effective consumer relaxers from overhyped ones.
After evaluating five top-selling formulas on curl texture compatibility, conditioning depth, and processing consistency, this guide delivers the strongest recommendation for the best hair relaxer for curly hair available right now.
How To Choose The Best Hair Relaxer For Curly Hair
Selecting a relaxer for curly hair requires evaluating the alkaline agent (lye vs. no-lye), the intended curl pattern, and the presence of restorative oils. A poor match leads to over-processing, breakage, or poor straightening results. Focus on these three factors to make an informed choice.
Lye vs. No-Lye: Which Is Safer for Curly Textures?
Lye relaxers (sodium hydroxide) provide stronger, faster straightening but increase the risk of chemical burns and scalp irritation, especially on sensitive skin. No-lye relaxers use guanine hydroxide or calcium hydroxide, which are gentler on the scalp but require thorough conditioning afterward to prevent dryness. For home use on curly hair, no-lye formulations with deep conditioners are the safer, more forgiving choice.
Matching Strength to Your Curl Pattern
Relaxer strengths are labeled Super for coarse, tightly coiled hair, Regular for medium curl textures, and Mild for fine or previously relaxed hair. Using a strength too harsh for your curl type causes breakage, while an underwhelming strength requires multiple rounds of application, increasing scalp exposure. Stick to Super strength for thick, resistant curls and lower strengths for looser waves or finer strands.
Conditioning Ingredients That Prevent Brittleness
After relaxing, the hair cuticle remains lifted and vulnerable to moisture loss. Formulas containing olive oil, shea butter, or specialized hydrating emollients reduce post-relaxer stiffness and breakage. A kit that includes a deep conditioner or a separate conditioning step is critical for preserving hair elasticity and shine.

In‑Depth Reviews
1. Motions Professional Hair Relaxer Smooth & Silken Super
Motions has long been a staple in the relaxer category, and this Smooth & Silken Super formula earns its leading spot through targeted chemistry. It’s specifically formulated for resistant, coarse, non-porous hair — exactly the curl texture that frustrates weaker relaxers. The hydrating emollient blend maximizes moisture retention during the processing window, reducing the straw-like brittleness common with super-strength formulations.
At 15 ounces, this is a generous size for those with thicker hair who want a single application or a couple of touch-ups. Being a no-mix, ready-to-use cream simplifies the process, which matters when you’re working through tight coils. Multiple user reviews confirm a single bottle lasts two months or more with salon-assisted application, and the straightening results hold without reversion for weeks.
The primary drawback is that this product has been flagged as potentially discontinued by the manufacturer, so stock availability may fluctuate. Users who can find it report consistent performance without scalp irritation when used correctly, making it a formidable choice for anyone seeking deep straightening power on dense curls.
Why it’s great
- Designed specifically for resistant, coarse curls
- No mixing required — apply directly from container
- Hydrating emollients prevent extreme dryness
Good to know
- Labeled as possibly discontinued; check current stock
- Not suitable for fine or previously damaged hair
2. Originals by Africa’s Best Olive Oil Hair Relaxer Kit
Africa’s Best delivers a complete no-lye relaxer kit that combines professional-grade straightening with the moisturizing punch of extra virgin olive oil. This Super/Coarse system targets the thickest curly textures and promises anti-breakage benefits, which is exactly what dense coils need post-processing. Users report that the creamy formula applies smoothly, processes fast, and leaves hair feeling soft and pliable rather than stiff.
The kit format includes everything needed for a full at-home relaxer session, eliminating guesswork about which separate conditioner to buy. Multiple customer reviews highlight that instructions are clear, and the results are reliably silky with a noticeable sheen. A significant number of repeat buyers confirm they’ve relied on this kit for years without formula changes that compromise performance.
A few users noted a reformulation that caused mild scalp tingling, suggesting that batch consistency may vary. For those with sensitive scalps, a patch test before full application is wise. Overall, this remains one of the most cost-effective options for delivering salon-quality straightening on tight coils.
Why it’s great
- Complete kit with relaxer, activator, and conditioner
- Extra virgin olive oil reduces breakage risk
- Fast processing time for thick, coarse hair
Good to know
- Some batches may cause mild scalp tingling
- Not ideal for those with very sensitive skin
3. ORS Olive Oil Professional Creme Relaxer Extra Strength
ORS is a heavyweight name in professional relaxers, and this Extra Strength creme formula holds its reputation well. An 18.7-ounce tub provides ample product for multiple applications, making it a practical choice for those who relax regularly or have very dense curly hair. The olive oil base helps maintain manageability, and users consistently report seriously straight results that eliminate the need for frequent flat-iron touch-ups.
Where this formula stands out is in its long-lasting shine. Customer reviews specifically mention that hair appears glossy and healthy weeks after application, indicating that the conditioning ingredients penetrate deeper than many competitors. The cream texture is thick enough to stay in place during processing, reducing the risk of uneven straightening that plagues thinner relaxers.
A potential hitch is labeling inconsistency — some packages arrive with a “Regular Strength” sticker over the “Extra Strength” designation, creating confusion about potency. Double-check the outer packaging before use. Additionally, users with the driest curls should pair this with an intensive deep conditioner to offset initial dryness, as the relaxer alone can leave hair feeling brittle if left on too long.
Why it’s great
- Large tub size offers great value per ounce
- Delivers glass-like shine and long-lasting straightness
- Thick cream reduces application errors
Good to know
- Labeling inconsistencies between regular and extra strength
- May require separate deep conditioner for maximum moisture
4. Luster’s Shortlooks Color Relaxer 3-n-1 Diamond Black
Luster’s Shortlooks breaks the mold by combining a relaxer, color, and conditioner into one step. The Diamond Black shade delivers an intense jet-black tint that covers grays while simultaneously straightening the hair. This saves significant time for those who typically separate coloring and relaxing into two appointments, and users consistently praise the lack of harsh chemical odor during the process.
The formula is designed for all hair types, but it works especially well on medium-density curls that don’t require aggressive straightening. Customer reviews mention that the straightening effect is moderate — it relaxes the curl enough to be manageable without making hair completely poker-straight. For those seeking a more natural, movement-filled finish with the bonus of rich color, this dual-purpose product is hard to beat.
One recurring note is that the straightening power is not as intense as dedicated relaxers like the Motions or ORS options. If your goal is bone-straight hair from tight coils, this isn’t the strongest choice. Also, the conditioning benefit is decent but not deep enough for very dry curl patterns, so follow-up moisturizing is still recommended.
Why it’s great
- Relaxes and colors in a single application
- No chemical odor during processing
- Leaves a rich, natural-looking black shade
Good to know
- Straightening effect is moderate, not maximum
- Color options limited to Diamond Black
5. African Pride Olive Miracle Deep Conditioning No-Lye Relaxer – Super Kit
African Pride’s Olive Miracle Super Kit focuses heavily on the conditioning phase, which is critical for maintaining hair integrity after chemical relaxing. The no-lye formula paired with a dedicated deep conditioner leaves even thick, puffy curls feeling soft and shiny rather than brittle. Users report that processing takes under 20 minutes on resistant hair, which is fast compared to many competitors, reducing scalp exposure time.
The kit includes eight components, providing everything from the relaxer cream to neutralizing shampoo and intensive conditioner. This completeness is particularly valuable for beginners who want professional-grade results without hunting for separate supplies. Reviews emphasize that the scent is pleasant and the creamy texture spreads easily through dense sections, allowing even application on stubborn coils.
A strong chemical fume is noted during processing, so proper ventilation is mandatory. Some users experienced scalp burning if the product was left on beyond the recommended window, suggesting that timing precision is critical. For those who follow directions closely, the results are remarkably smooth with minimal post-relaxer shedding.
Why it’s great
- Complete 8-piece kit offers excellent convenience
- Fast processing time for thick, resistant hair
- Deep conditioner leaves hair soft and flexible
Good to know
- Strong chemical odor requires good ventilation
- Risk of scalp burn if application timing is off
