Redken All Soft Mega Mask review for very dry hair

Redken All Soft Mega Mask is a heavy, two-formula treatment for thick, coarse hair that feels like rope when it dries, and on that hair it does a lot. Fine hair should keep walking. We'd put it at 4.1 out of 5, a high mark for how well it softens the hair it was designed for, trimmed for its weight and a fragrance load that won't suit sensitive scalps.

It comes in a dual-chamber tube, and you can see the Redken Mega Mask on Amazon, where availability shifts because the Mega line has been around for years and sizes come and go.

Two formulas in one squeeze

Squeeze the tube and two formulas come out side by side, one from an outer chamber and one from a core running down the middle. Redken describes the pairing as a deep conditioning mask combined with a care extender, and it says the soft, sleek finish lasts through three washes. The All Soft Mega line is aimed at severely dry, coarse hair, and the brand credits a superfood blend of cactus extract, aloe vera and sacha inchi oil along with its RCT Protein Complex.

Read the two labels, which Redken publishes separately, and the plant extracts sit well down the lists, with the cactus and aloe coming after the fragrance allergens. They're there for the story more than the softness. The real work happens in the conditioning agents and oils near the top of each list.

Rich cream on towel-dried hair, with an extra step

Expect a thick, rich cream that clings to the hair rather than sliding off it. Redken doesn't publish scent notes for this one, but fragrance and several named allergens appear on the inner formula's label, so expect a noticeable, lingering scent rather than a faint one.

The directions are unusual. Redken's listing says to apply the mask after conditioning, on clean towel-dried hair, then rinse and style. Most masks replace conditioner, and this one goes on top of it. Some retailer pages add a 3 to 5 minute wait before rinsing, which is a sensible target, and an Australian retailer passes along a suggestion to use it every third wash, which fits the three-wash claim.

Squeeze until both chambers come out evenly and rub the two together in your palms before applying, so you're not putting all the extender on one section and all the mask on another. Towel-drying first matters with a mask this rich, since less water on the hair means less dilution. Expect to need a good palmful for thick shoulder-length hair, and rinse well, because a formula built to hang on doesn't leave with a quick splash.

Softer lengths that hold up between washes

On coarse, dry hair, the payoff should be obvious after the first use. Hair that felt rough and straw-like should feel softer and comb out more easily, with less frizz once it's dry and more shine along the lengths. If the extender does what Redken says, some of that should carry into the next two washes instead of vanishing after one shampoo.

The inner formula leans on amodimethicone, an amino silicone that clings to the most damaged parts of the strand and smooths them flat. The outer formula carries mineral oil fourth on its list, and mineral oil sits on the surface to slow water loss, which is exactly what very dry, coarse hair needs. That outer chamber also holds a silane, an ingredient that can bond to the hair surface and form a thin film, and that kind of grip is the most plausible reason the effect could last past a single wash. The three-wash figure is Redken's own, and the label alone can't confirm it.

Where Redken earns its score

For the target hair, it's hard to fault. Pairing a sealing oil with a film-forming extender is a smart design for hair that loses moisture the moment you step out of the shower. The outer formula is kept acidic with lactic and citric acid, which helps the cuticle lie flat and adds shine. Using it every third wash also means a tube lasts longer than you might expect from a mask this rich.

It's also unusually transparent. Publishing a separate ingredient list for each chamber lets you see what each half is doing, which most two-part products don't bother with.

The trade-offs

Weight is the main one. Mineral oil layered with amodimethicone is a lot of coating, and on fine hair or a scalp that turns oily by afternoon, it tends to read as limp rather than soft. Keep it on the mid-lengths and ends no matter what your hair type.

Fragrance comes next. The inner chamber lists several allergens, which is a real drawback for sensitive scalps. Some shoppers also avoid mineral oil on principle. It's stable and rarely irritating, but if your routine excludes it, this mask is out. The conditioner-then-mask routine is a smaller annoyance, adding a few minutes and a little more product to every session.

Thick, coarse hair is the target

Buy it if your hair is thick and coarse and feels rough and dull, especially if it's been colored or blown out often. Very dry wavy hair with a lot of density can do well with it too.

Skip it if your hair is fine or oily at the root, or if mineral oil and heavy fragrance are on your avoid list. In those cases a lighter, simpler mask will give you softness without the drag.

How it stacks up against Nexxus Keraphix and Redken's All-In Mask

Nexxus Keraphix Masque goes after damage with keratin and other proteins in a small single-use pouch. It's the better choice for bleached hair that feels mushy and weak, where protein helps. Redken's mask is the better choice for hair that's intact but parched and coarse, where sealing and softness matter more than strength.

On Redken's own shelf, the All Soft All-In Mask is the obvious sibling to look at if the Mega Mask is hard to find. If you'd like to compare before committing, you can check the Mega Mask on Amazon and see which sizes are in stock.

Redken Mega Mask is worth it for coarse, parched hair and wrong for fine strands

Shampoo, condition, towel-dry, then apply a palmful of the mixed formulas through the mid-lengths and ends. Leave it on for a few minutes, rinse well, and repeat every third wash so the extender has a chance to carry you between treatments. For thick, dry hair it's a strong 4.1 in our book, and you can order the Redken mask here.
