I can honestly say that this works so much better than any other deep conditioner that I have either made or bought. I don't get too caught up in the "expensive is better" or "cheap products are junk" debate. I use what works for my hair and this definitely does an excellent job of moisturizing my hair and making it shiny. It only leave it on for the length of my shower and wow!"

Amazon shoppers have granted this heavenly-smelling deep conditioner 4.6 out of 5 stars for how effective it is. The $16 product works wonders at preventing hair thinning, shedding, and breakage. The mango butter acts as a nice emollient to lock in all the moisture.

Promising review: "It’s difficult to find a deep conditioner that actually brings moisture to my hair and revives it. I kinda followed the instructions on the label but I left it on longer than stated. It’s thick and I feel like that’s what my hair needed. I rinsed my hair, dried it with a towel mannn I didn’t have to do much untangling!! It left my hair soft and easy to comb through. I’m now looking to purchase some of the other products."

SheaMoisture Intensive Hydration Hair Masque

SheaMoisture is one of my favorite hair care brands because every one of their products I've tried actually do what they say they do. This 4.6-star hair mask is no exception – it truly does provide "intensive" hair repair and hydration. The formula with manuka honey and mafura oil is friendly on over-processed, damaged, or color-treated hair and helps you build stronger, healthier, and frizz-free strands.

Promising review: "i have naturally wavy/curly hair but i damaged it so bad with bleach that they kind of went away. i did a lot of hair masks, gave it a lot of time to breathe, etc etc etc and this is the only thing to come close to restoring my natural curl pattern. it smells amazing, helps with frizziness, and definitely helps my hair feel healthier, moisturized, and as shiny as it can be. i also notice that it's better than a lot of other products when it comes to maintaining hair color. my dyed hair doesn't bleed or become discolored with this product. love the ingredients too!! phenomenal brand and product overall."

Unove Deep Damage Hair Treatment Mask

This 4.6-star pick comes complete with highly-concentrated proteins that seep deep into your locks for noticeable shine and hydration.

It also smells ahh-mazing with notes of citrus and flowers.

Promising review: "This is my favorite treatment I’ve ever used. My hair is thick and dry, but this product makes it feel soft and manageable. It seems to reduce damage as well; every time I go to the salon, my stylist comments on how strong and healthy my hair looks. The scent is just right—not too strong, which I appreciate."

It's safe for all hair types, too, so you could easily share the love with your roomie or S.O.

Arvazallia Hydrating Argan Oil Hair Mask + Deep Conditioner

This $13 deep conditioner leaves your locks with such a luxurious feel, thanks to the strengthening and hydrating argan oil. The shine it gives is also impeccable! Shoppers have given it 4.5 out of 5 stars for its rich texture, effectiveness, and its ability to deliver "salon-quality" results.

Promising review: "My hair is three feet long. I use this generously around every couple weeks after I shampoo. I get as much water out of my hair, I slather on about half the tub (again, my hair is very long). I leave it in while I shave and soap up and rinse. Then I rinse it out. One side bonus is that it makes the skin on my body so soft. The smell is beautiful and I get comments about the nice smell. The end result is that my hair flows from the top to bottom. The areas that tend to look a little dry (bottom) look just as shiny and moisturized as the rest of my hair. I will use this the rest of my life and recommend it to everyone."

OUAI Thick Hair Mask

If you want your locks to look and feel expensive, this 4.5-star OUAI hair mask is the way to go. Just one use will leave your hair feeling smoother, softer, and stronger. The formula includes ilipe and shea butters to condition, almond, olive, and macadamia oils to soften and smooth, and hydrolyzed keratin to prevent breakage.

Promising review: "I have oily scalp and dry ends. My end are so dry that they soak up water and takes hours to air dry. I used this today for the first time and my hair air dried 50% faster than normal. My hair feels soft, but not oily. This is my new favorite hair product!"

Has Gemma been an innie the whole time?

TikTok user @msauroraalice made the connection that Severance season 2 episode 9, "The After Hours," has the same title as a specific Twilight Zone episode in which a mannequin, well, forgets she's a mannequin. And now we're all wondering whether Severance is going to reveal a very similar plotline with Gemma.

"Could Gemma have been manufactured at Lumon and all of her experience with Mark is just a severed version of herself," @msauroraalice says, theorizing that "there is no Gemma."

"I bet this next episode, Gemma or Helly has a horrifying discovery about themselves just like the mannequin realizing she's not even alive," she continues.

Clearly, this Twilight Zone episode has a ton of similarities to Severance, with the split identities of it all. And as one Reddit user just made it even more heartbreaking by saying, "She could be an experiment from the very start which is why they went as far as to fake her death and recruit Mark to work for them. That would be heartbreaking. It would mean Mark and Gemma 's relationship was manufactured from the beginning."

"The After Hours" is sure to set us up for a crazy 'Severance' season 2 finale.

After everything Mark has been through, this would truly be a heartbreaking turn of events and I don't know if I could handle it! I'm not alone, either. TikTok users flooded the comments of the post (which has over 900K views).

"If Gemma was never a full person to begin with I'm gonna lose my mind," one user said, while another theorized, "I think Gemma is real but she actually died. Lumon had plans for her to begin with so they revived her body because they effectively own it and now she's stuck in purgatory testing."

But if this Severance theory breaks your heart as much as it breaks mine, there's a silver lining. "The next episode after 'The After Hours' from TWZ is called 'The Mighty Casey' and is about a robot who becomes more human I believe," a third TikTok user says.

But honestly, emotional devastation — and peeling back a character's insecurities, fears, and heartbreak to get to their core — make for really good TV because of how relatable those moments can be. So we'll just have to see what the Severance season 2 finale has in store.
