Heaviness barely separates these three deep conditioner masks. Only 36 of 3,978 usable Ulta reviews called one greasy, heavy, limp or coating. Softness went to amika soulfood (paid link) (46% of 2,411), moisture and rebuys to SheaMoisture Manuka Honey (paid link) (37% and 31% of 259, mostly older reviews), and strength to Mielle Rosemary Mint (paid link) (13% of 1,308).

Which deep conditioner left hair soft without weighing it down?

Weight turned out to be the wrong worry for these three deep conditioner masks. Across 3,978 usable Ulta reviews, 36 said one left hair greasy, heavy, limp or coated, split 10 for Mielle, 9 for SheaMoisture and 17 for amika. The split was in the praise. Reviewers called their hair soft, silky or smooth in 46% of amika reviews, against 38% for SheaMoisture and 29% for Mielle. Moisture ran the other way, with SheaMoisture at 37%, Mielle at 28% and amika at 22%.

Repurchase talk was lopsided too. 31% of SheaMoisture reviewers said they would buy it again or called it a staple, about double the 15% for each of the other two, though 215 of its 259 usable reviews date from 2015 to 2019.

Our default pick is amika soulfood, for the steadiest soft-hair praise on the largest base. Its caveat is that nearly all its Ulta reviews were first posted on amika's own site. [R-ULT-MIE] [R-ULT-SHM] [R-ULT-AMI]

Why 1,504 of the 5,482 Ulta reviews did not count

We read every review each Ulta page would show on October 31, 2026, newest first. Ulta gives older dates only as a number of years ago, so every year in this article is approximate. SheaMoisture's page held 266 reviews and Mielle's loaded 2,750. The amika page lists 2,516 but stalled near review 1,085, so we read the rest oldest first, 2,466 distinct reviews in all.

Mielle's page was the messiest. 909 reviews were about other Mielle items, mostly the Rosemary Mint edge gel Ulta shows on the same page. In four 2026 months most reviews were free products, so each whole month went. May held 75 reviews (67 free), July 109 (104), August 17 (10) and October 240 (179). August fell below our automatic 20-review cutoff, but more than half of it was free, so we dropped it by hand.

Those 441 reviews held 4 one- or two-star ratings (2 in August, 2 in October), and none of the 72 that would otherwise have counted gave one or two stars, against 4% of the Mielle reviews we kept. Another 29 free reviews from other months also came out. What remains is mostly from 2018 to 2023, with only 40 usable reviews from about 2024 on. [R-ULT-MIE]

Ulta marks 2,419 of the 2,466 amika reviews we read as Syndicated Amika, meaning they were first posted on amika's own site. We counted them because they describe this mask, but brand-site reviews can lean positive, and only 22 of 2,411 usable ones gave one or two stars (1%, against 4% for Mielle and 5% for SheaMoisture). SheaMoisture lost just 7 reviews, none free, and 136 carried Ulta's Verified Buyer badge. [R-ULT-SHM] [R-ULT-AMI]

How each deep conditioner feels after you rinse it out

Soft, silky or smooth hair topped all three, narrowly so for Mielle and SheaMoisture, where moisture ran a point behind. SheaMoisture reviewers were the likeliest to say their hair felt hydrated and that it combed through easily (14%, against 9% for Mielle and 5% for amika). Shine came up for amika and SheaMoisture at 10% each and less often for Mielle (6%).

Hair left dry, stiff, straw-like or tangled came up 30 times for Mielle, 5 for SheaMoisture and 10 for amika, and 72 reviewers across the three said a mask did nothing or left hair still dry.

Reviewers liked amika's scent a little more often (32%) than SheaMoisture's (28%) or Mielle's (23%). SheaMoisture also drew the most scent complaints by share, 11 of 259, the same count as Mielle had across five times as many reviews. [R-ULT-MIE] [R-ULT-SHM] [R-ULT-AMI]

Mielle Rosemary Mint hair mask reviews, minus the free jars

Mielle's Amazon listing names biotin, rosemary, sesame seed oil, honey and certified organic coconut oil, and says the mask helps promote stronger, longer-looking hair. It targets all hair types, especially 3A to 4C, chemically treated hair, braids and weaves, and says to leave it on 15 to 20 minutes after shampooing. We link the 12 oz jar sold and shipped by Amazon.com. Amazon titles it Mielle Organics Rosemary Mint Hair Mask with Biotin, while Ulta calls it Mielle Rosemary Mint Strengthening Hair Masque. [A1]

Strength was where Mielle stood out. 169 of 1,308 usable reviews (13%) said hair felt stronger, broke less or felt repaired, against 7% for amika and 5% for SheaMoisture. Another 131 (10%) said their hair grew or shed less. We report that only as their claim and cannot verify it, and 10 reviewers blamed shedding on the mask.

Ratings slipped over time. One- and two-star reviews made up 3% of 799 usable reviews through 2020 and 6% of 469 from 2021 to 2023. From about 2024 on, 9 of just 40 were one or two stars, and 8 said the mask left hair dry, stiff, straw-like or tangled. That is too few to call a trend. [R-ULT-MIE]

Buy it if breakage is your main complaint and you have curls or coils, where 37% of 185 curly-haired reviewers reported less frizz or better-defined curls. Skip it if you want recent reviews you can lean on, or if a 15- to 20-minute wait does not fit your routine.

Why SheaMoisture Manuka Honey still scores well, years later

SheaMoisture pitches this masque on Amazon at hair thirsty for moisture, especially curls, promising intense conditioning and saying it leaves over-processed, damaged or color-treated hair stronger, healthier and frizz-free. It names shea butter, honey, mafura and baobab oils and African rock fig, with no sulfates, parabens, phthalates, mineral oil or petrolatum. Directions call for clean wet hair, a wide-tooth comb and five minutes. We link the 11.5 oz jar sold by Amazon.com, which Amazon titles with Intensive Hydration Hair Masque first and Ulta with Manuka Honey & Mafura Oil first. [A2]

Across 259 usable reviews, 37% said hair felt moisturized and 38% soft, silky or smooth. It led on detangling and was roughly level with Mielle on less frizz or more defined curls (15% against 12%). Complaints were few, though its shares for disliking the smell (4%, 11 reviewers), heaviness (3%, 9) and doing nothing (3%, 9) were the highest of the three.

Age is the real limit, since almost any Shea Moisture Manuka Honey masque review on Ulta is years old. By Ulta's approximate years, 215 of the 259 usable reviews come from 2015 to 2019 and only 44 from 2021 on, with 1 of those 44 giving one or two stars. Nobody said the formula had changed, but with so few recent reviews that silence tells us little. [R-ULT-SHM]

We would reach for it if your curls run dry and you want a five-minute step, and pass if you need a large, recent body of reviews or have fine hair, where 3 of only 16 fine-haired reviewers called it heavy.

Is the amika soulfood nourishing mask review data too rosy?

On Amazon, amika describes soulfood as a rich, moisturizing formula that leaves hair manageable, soft and shiny for days, for all hair types and especially hair that needs deep hydration. It credits vitamins and nutrients without naming them and, in the details we recorded, gives no leave-on time. We link the 8 fl oz jar sold by Amazon.com, which Ulta sells as amika Soulfood Nourishing Mask 8.0 oz. [A3]

Soft, silky or smooth hair came up in 1,107 of 2,411 usable reviews, and 32% liked the smell. Moisture mentions were lower at 22%, while detangling (5%) and frizz or curl definition (6%) trailed the other two. Only 17 reviewers called it heavy, and 14 said price or size was a real drawback.

Newer amika reviews run a little cooler. Those from about 2024 on described soft hair 38% of the time, against 48% through 2020, and their one- and two-star share rose from 1% to 3% across 371 reviews. [R-ULT-AMI]

Choose it for fine or color-treated hair when you want softness without weight. Look elsewhere if detangling is the main job. Across all reviews it drew that praise from 5%, against 14% for SheaMoisture, and among curly-haired reviewers 12% against 16%.

For curls and coils, moisture or strength?

Both listings aim at curls, so for Mielle vs Shea Moisture we looked at reviewers who said their hair is curly, coily or wavy: 185 for Mielle and 91 for SheaMoisture. SheaMoisture's curly group described soft or moisturized hair 70% of the time, against 55% for Mielle, and 43% said they would buy it again, against 17%.

Mielle's curly reviewers reported less frizz or better-defined curls at 37%, close to SheaMoisture's 33%, and 24 of them mentioned stronger hair or less breakage. Heaviness is where SheaMoisture slipped, with 7 of its 91 curly reviewers calling it heavy or greasy, against 2 for Mielle. [R-ULT-MIE] [R-ULT-SHM]

Time on the hair differs a lot, 15 to 20 minutes for Mielle against five for SheaMoisture. For curls we would choose SheaMoisture when moisture matters most, and Mielle when breakage worries you more, knowing its recent reviews are few.

Choosing a deep conditioner for dry damaged hair, color or fine strands

Reviewers who said their hair is dry or damaged reacted almost the same way to all three. Soft or moisturized hair came up for 70% of 282 on amika's page, 71% of 59 for SheaMoisture and 69% of 64 for Mielle. Strength split them, named by 25% of the Mielle group and 23% of the amika group but 14% for SheaMoisture.

Color-treated, bleached or chemically treated hair is where amika has real depth, with 222 such reviewers. Of those, 49% described soft, silky or smooth hair, 19% said it felt stronger, and 3 called it heavy. SheaMoisture (32) and Mielle (29) had too few to compare, though their listings name color-treated and chemically treated hair.

For fine hair, amika has the only sizable record. Its 89 fine-haired reviewers described soft or moisturized hair 63% of the time and 2 called it heavy, while SheaMoisture (16) and Mielle (17) had too few to rank. Porosity is the hardest call. Only 24 Mielle, 9 SheaMoisture and 2 amika reviewers said they have low porosity hair, and 5 on each page said high porosity. Mielle's listing names both, but these groups are far too small to back that up or rule it out.

On time, SheaMoisture's five minutes is the easiest to fit into a shower, Mielle asks for three to four times as long, and the amika details we recorded give no time, so follow the jar. [R-ULT-MIE] [R-ULT-SHM] [R-ULT-AMI] [A1] [A2] [A3]

Frequently asked questions

Is amika soulfood good for fine hair?

It has the only sizable fine-hair record of the three. Of 89 reviewers who said they have fine or thin hair, 42 (47%) described soft, silky or smooth hair and 2 called it heavy or greasy. Mielle had 17 fine-haired reviewers and SheaMoisture 16, too few to compare, though 12 of SheaMoisture's 16 described soft or moisturized hair.

Is Shea Moisture Manuka Honey good for curly hair?

Its curly-haired reviewers were the most positive curly group on moisture and rebuys. Of 91, 70% said hair felt soft or moisturized, 33% saw less frizz or better-defined curls and 43% said they would buy it again, while 7 found it heavy. Most of these reviews date from about 2015 to 2019.

Is Mielle Rosemary Mint hair mask good for breakage?

It drew the most strength comments of the three. 169 of 1,308 usable reviews (13%) said hair felt stronger, broke less or felt repaired, against 7% for amika and 5% for SheaMoisture. Only 40 usable Mielle reviews date from about 2024 on, and 9 of those gave one or two stars.

Do reviewers say Mielle Rosemary Mint grows hair?

Some do. 131 of 1,308 usable reviews (10%) said their hair grew or shed less, while 10 blamed shedding on the mask. We cannot verify either claim. The Amazon listing describes a mask that hydrates dry, brittle strands and reinforces strength, and its hair wording stops at stronger, longer-looking hair, not growth.

Which deep conditioner is least likely to weigh hair down?

None of the three drew many weight complaints. 17 of 2,411 amika reviews and 10 of 1,308 Mielle reviews (1% each) called the mask greasy, heavy, limp or coating, against 9 of 259 for SheaMoisture (3%). On amika's page, 2 of 89 fine-haired reviewers found it heavy.

Why did we set aside so many Mielle reviews?

Because 909 of the 2,750 reviews on Ulta's Mielle page were about other Mielle items, mostly the Rosemary Mint edge gel. Another 441 came from four 2026 months when most reviews were free products (May, July, August and October), and 29 more free reviews came from other months. We also dropped 63 that were unused, shipping-only, repeated, empty or not in English. That left 1,308 usable, most from 2018 to 2023.
