One of the biggest hacks that has kept my highlighted, fine hair healthy over the years is using a hair mask instead of conditioner. While you can totally use a hair mask as a weekly deep conditioning treatment (and I do), I also love how it gives my hair a little extra TLC without leaving my strands feeling greasy, weighed down, or waxy.

Don’t get me wrong - I love conditioner - but hair masks are a secret weapon for adding shine and nourishment, preventing breakage, and healing damage, especially if you heat style your hair regularly like I do. Add in the fact that environmental factors can also cause damage (harsh, cold winter climates or extra UV rays in the summertime), and I think it’s safe to say that everyone would benefit from adding a hair mask to their routine.

Two of my favorites that I find worth the money are the Amika Soulfood Nourishing Mask and the Ouai Treatment Masque. Also among Sephora’s bestsellers, these masks seem similar because they provide hydration and make your hair soft, but they’re actually quite different.

You don’t necessary need both, so today I wanted to really dive into these products and share everything you need to know so you can pick the right mask for you. Whether you need a mask that repairs damage or strengthens, adds shine, or is gentle enough to use a few times a week, this is my full comparison and review.

Below, I share how the two hair masks compare, including ingredients, hydration levels, and which one will give you the best results depending on your hair type.

amika soulfood vs ouai hair mask: which deep conditioner is better?

amika soulfood hair mask

The Amika Soulfood Nourishing Mask is a deep conditioning treatment designed to restore hydration, smooth frizz, and improve softness.

It’s known for its rich, creamy texture - truly, it’s like butter, though I know everyone uses that term in the beauty world. But trust me, this coats your hair thoroughly and helps replenish moisture after heat styling, coloring, or dryness.

Key features include:

Deeply hydrating formula
Rich conditioning texture; truly feels like a mask, not a thick conditioner
Helps smooth frizz and improve shine
Safe for color-treated hair

Because it focuses heavily on hydration, this mask is especially popular for dry, thick, or frizzy hair. I love to use this after a season of lots of heat styling (like the holidays), or when I’ve been swimming or traveling a lot as part of my post-travel reset routine. Truly nourishing, this feels like a salon treatment you can do at home.

pros

Deeply hydrating
Rich conditioning texture (like butter)
Leaves hair very soft and nourished
Great for dry or frizzy hair

cons

Can feel heavy on very fine hair (in that case, you may prefer Amika’s The Kure mask - check out how it compares to Soulfood here).
Richer texture may weigh down thin strands
Doesn’t leave a film, but the extra hydration may make it harder for straight hair to hold a curl after

ouai hair mask

The Ouai Treatment Masque is a strengthening hair mask designed to repair damage while improving softness and shine. It comes in two versions (Fine to Medium as well as Thick) to address all hair types, and I’d say it’s much more lightweight than Soulfood. You still get nourishment, but it feels like a thicker conditioner rather than a mask.

Key features include:

Helps repair damaged hair
Strengthens hair
Smooths frizz
Works well for color-treated hair

I love to use this mask whenever I travel and am dealing with the harsher hotel water, as it provides more hydration than a standard conditioner, but isn’t so thick that it’ll weigh my hair down. Ouai’s mask focuses more on repair and strengthening than heavy moisture, so it’s perfect if you heat-style regularly or are exposed to harsher elements (hard water, drying temperatures, etc.).

pros

Helps strengthen damaged hair
Lightweight compared to many hair masks; feels like a thicker conditioner
Smooths frizz
Adds a little shine
Works well for fine or damaged hair

cons

Not as intensely hydrating as some masks
May not be rich enough for extremely dry hair
Leans more towards deep conditioner than mask treatment

key differences between amika soulfood and ouai hair mask

Even though both products fall into the hair mask category, they’re formulated with slightly different goals in mind. Because of its richer hydration, Amika Soulfood usually works best for dry, thick, or frizzy hair. I personally have fine hair and love to use this mask when my hair needs a good reset, so don’t let the word “rich” make you think it’ll weigh your hair down.

The Ouai Treatment Masque works to address damage, so it’s best for chemically treated or weaker hair that needs strengthening. They make both Fine to Medium and Thick versions, so it’s perfect for all hair types.

ingredients comparison

Both brands use salon-quality ingredients, so they feel truly luxurious, but their formulas focus on different benefits.

The Amika Soulfood Nourishing Mask includes deeply conditioning ingredients that help smooth and soften:

Jojoba Seed Oil - moisturizes and softens.
Sea Buckthorn - helps to nourish and restore lipids in hair.

The Ouai Treatment Mask focuses more on repairing ingredients, rather than just moisture:

Shea Butter - hydrates, softens, and conditions dry, over-processed hair.
Panthenol - restores shine while improving overall strength of hair strands.
Hydrolyzed Keratin and Protein - prevent breakage while reducing frizz and flyaways.

The Ouai Treatment Masque works to repair, whereas the Amika Soulfood Nourishing Mask is a true deep conditioning mask.

price

I’m a nerd who likes to really get granular when it comes to price. The Amika Soulfood Nourishing Mask costs $36 for 8oz, or $4.50 per ounce. The Ouai Treatment Masque retails for $38 for an 8oz container, or $4.75 per ounce. So whether you factor in up-front cost or price per ounce, the Amika Soulfood Nourishing Mask is cheaper. While I don’t measure how much I use, I will also say that you don’t need as much of the Amika Soulfood Mask so one jar will last you a little longer, making it the better value all around.

texture

While the term is overused in the beauty world, the Amika Soulfood Nourishing Mask truly feels like butter. It’s thick, but melts into the hair beautifully and is such a dream to use, even if you have fine hair like me. The Ouai Treatment Masque is much closer to a conditioner as far as consistency goes; it’s creamy, but not thick (even the Thick Mask). It works into your hair easily, but isn’t a heavy-duty repair mask.

hydration and repair

The Amika Soulfood Mask is primarily designed to deeply hydrate hair and improve softness, while the Ouai Treatment Masque, focuses more on strengthening damaged hair while still adding moisture.

If you heat style your hair frequently, get the Ouai Treatment Masque. If your hair feels dry, brittle, or frizzy, I recommend the Amika Soulfood Mask.

Need shine, rather than just hydration? Both brands make glosses, which are one of my favorite at-home treatments - I compare them in my guide to Amika Gloss vs Ouai Gloss.

results

Both masks provide noticeable results, which I appreciate - nothing worse than buying something and feeling like it didn’t do anything.

The Amika Soulfood mask makes your hair soft, smooth, hydrated, and less frizzy. It’s a true deep conditioning treatment, so you’ll really notice a change if your hair feels dry or brittle.

On the other hand, the Ouai Treatment Masque makes your hair feel smoother and nourished, but the results don’t feel as heavy. The mask focuses more on strengthening your hair, so you will notice that over time, but not necessarily after one use. I’ve noticed less breakage in my highlights since I started using it consistently.

which hair mask is better for fine hair?

The Ouai Treatment Masque is often the better option because it has a slightly lighter texture, it’s less likely to weigh hair down. That said, I have fine hair and also love using the Amika Soulfood Nourishing Mask when my hair needs a deep reset. If you’re worried about it weighing down your hair, use a small amount and focus on mid-lengths to ends.

That said, if you want an Amika mask but don’t want to worry about it weighing down your fine hair, I also LOVE The Kure mask - check out how it compares to Soulfood here.

which hair mask is better for thick hair?

If you have thick hair, you can honestly use either mask. Pick Ouai Treatment Masque if you heat-style your hair frequently or want to address damage; if your hair feels extra frizzy, go with Amika Soulfood Nourishing Mask.

which hair mask is better for dry or damaged hair?

For very dry hair, get the Amika Soulfood mask for its deeply moisturizing formula.

If your hair instead feels damaged, get the Ouai Treatment Masque is a better choice because it focuses on strengthening the hair.

If your hair is both dry and damaged, you can alternate between both masks for the best of both worlds and optimal results. Or go back to your hair type - fine hair = Ouai Treatment Masque, thick hair = Amika Soulfood mask.

which hair mask is better for frizzy hair?

The Amika Soulfood mask makes my hair less frizzy than the Ouai Treatment Masque because of its richer texture and formulation.

which hair mask makes your hair softer?

Honestly, both masks make your hair really soft, but if I had to pick one, I’d say Amika Soulfood mask is slightly more softening.

which hair mask is better for highlighted or color-treated hair?

If you have highlights or color-treated hair, I highly recommend the Ouai Treatment Masque. Using that in frequently/ instead of a normal conditioner really saved my hair and preventing breakage and damage for me, especially since I curl my hair almost every day.

I still love to use the Amika Soulfood Nourishing Mask as a treatment, but for consistent usage to protect your highlights and strengthen over time, Ouai wins.
