St. Ives packs its Apricot Scrub with crushed walnut shells that can tear up your face, and leave you wrinkled with acne ... according to 2 women gunning for the skin treatment.

In a lawsuit the women filed, they say the supposed exfoliating facial scrub feels like sandpaper to the skin, with similar results. To back up their claim, they say dermatology research warns walnut shells to the face can cause inflammation leading to breakouts, and accelerated aging.

Their main beef is the St. Ives product says it's "dermatologist tested" -- which is misleading, they say, because it is tested ... but NOT recommended.

They've filed a class action suit against parent company, Unilever, for more than $5 million.

It's Mariah Carey's world these days -- and MAC is just living in it.

Our cosmetics sources say Mariah's new makeup line is all her doing ... right down to the product names and how they're marketed at MAC stores.

We're told she came up with what each shade of lipstick or mascara would be called, and settled with names like Dahhlinggg, MCizzle and So Dramatique.

She even created an instruction manual of sorts for everyone peddling her products at MAC stores.

For the record, we're told MAC was happy to oblige on every front ... because, well, Mariah gets what Mariah wants.

The lawyers representing women who claim a L'Oréal hair relaxer burned their head aren't just suing -- now they're demanding an urgent recall of the product.

TMZ broke the story ... L'Oréal was sued for selling a celebrity-backed product called SoftSheen-Carson Optimum Amla Legend No-Mix, No-Lye Relaxer -- which the plaintiffs say singed their scalp and made them go bald.

L'Oréal fired back in docs, saying its packaging warns this very danger, and clearly instructs consumers on how to use it safely.

Ben Meiselas and Mark Geragos, who rep the alleged victims, say that's a load of BS ... and add L'Oréal is admitting the product has dangerous chemicals, despite advertising it "protects the scalp and skin."

Geragos' firm says it's downright absurd to blame the women harmed by the product, and they won't relax until the relaxer is completely pulled from the shelves.

Britney Spears celebrated her 35th birthday with roughly 20 thousand people Friday night, and revamped an old 'do for the occasion.

Spears performed at KIIS FM's Jingle Ball in L.A. -- along with Justin Bieber, Bruno Mars and a bunch of other huge acts -- and her double bun hairstyle made loyal fans nostalgic for that classic, often-imitated, never duplicated "school girl in pigtails" look.

Little messier these days, but still ... cue the track!

Kylie Jenner specializes in makeup, so she may want to seriously make up with one woman who's threatening to drop the legal hammer on her for ripping off her photos to promote Kylie's cosmetics line.

A woman named Vlada Haggerty says her Instagram is littered with photos of women striking various poses which accentuate their lips. The pics are striking ... pale women with dark lips and stuff like that.

Vlada and her professional photog claim Kylie has jacked the style of the photos to hawk her wares, and they're threatening a lawsuit. They say the pics are dead ringers for theirs.

Here's the problemo ... there's a whole legal thing that ideas are not legally protected -- just the images -- and Kylie did her own version that may be similar, but as Freud said, "close, but no cigar."

We reached out to Kylie's camp for comment ... so far, no word back.

Would-be hecklers and game-disrupters listen up ... THIS IS HOW IT'S DONE.

The victim is Portland Trailblazers star Allen Crabbe ... and here's video of him getting absolutely PUNISHED by a heckler during a game last week against the Memphis Grizzlies.

Subject of the heckle? Crabbe's Odell Beckham Jr.- inspired hairstyle ... and the smack talk is sooo good that at one point even Crabbe has to laugh.

BTW, Crabbe (who has a $75 million contract) had just 6 points in the game so ... mission accomplished, brother.

Marilyn Monroe's blonde wig from her last film, "The Misfits," is about to hit the auction block.

It's the first time in almost 2 decades the mop's been up for grabs. Bidding starts at $10k ... a lot less than the $29.9k it sold for last time around. Heritage Auctions, which is running the show, is counting on $20k minimum.

A lock of Lennon's hair sold for $35k earlier this year ... almost certainly more than MM's fake hair will fetch.

Marilyn's wig has some extras, like 5 ringlets for volume. You also get the original storage box labeled: "United Artists Corporation / The Misfits / Mapes Hotel / Reno, Nevada" and "Hold At Airport For Pick Up" ... so, cool piece of movie history.

Bidding starts Nov. 12.

Orlando Bloom has finally seen the light.

We got Katy Perry's BF Friday leaving the Andy LeCompte Salon in WeHo, where he got snipped and bleached.

Colton Haynes went to great lengths -- 2 weeks to be exact -- to pull off botched Miss Piggy.

The "Arrow" star went all out soliciting Bitemares makeup artist Erik Porn -- yup, his real name -- to apply the makeup during a 4-hour sitting. Colton and Erik worked together on "Teen Wolf" and Erik gave him the ultimate hookup.

The final product came together Saturday, but the grunt work started weeks before, when the head, chest and neck were molded. When it was all said and done they turned the sassy 'Muppet' into a plastic surgery nightmare.

Fetty Wap didn't dress up for the Lure Halloween party in Hollywood Saturday night, but he was almost unrecognizable with his fresh set of veneers.

As we reported, Fetty dropped $80k for his new set of shiners and his nonstop smile says it all ... money well spent.

Boston Celtics player Gerald Green was so stoked about kicking off the NBA season Wednesday night -- he braided a CLOVER into his hair ... and it was awesome.

By the way, it worked -- the Celtics beat the Nets and Green dropped 9 points!

The Kardashians' makeup artist is harassing her fiance's ex-wife and fat shaming his son, according to new legal docs.

Joyce Bonelli -- who flaunts her Kardashian ties on Instagram -- also used her social media to call Beth Taverniti a "handbag hoe" and a "ghetto bitch" ... according to Beth's request for a restraining order.

Beth also took their feud to court because she says Bonelli is bullying the son she has with Ben Taverniti, who's currently engaged to Bonelli. In the docs, Beth says Bonelli sent texts about the 5-year-old ... saying he's 45-60 pounds overweight and "the fat around his neck is getting so thick he doesn't breathe well."

Beth says Joyce has a huge following on social media -- including 1.7 million on IG -- because of her link to the Kardashians, which makes her posts way more humiliating.

Beth's restraining order request was denied, but there's a hearing later this month where she'll try to convince a judge she needs protection.

L'Oréal's got another angry customer ... and she says SHE has PHOTOGRAPHIC evidence the company burned her bald.

L'Oréal's pushing a hair relaxer called SoftSheen-Carson Optimum Amla Legend No-Mix, No-Lye Relaxer. Delicia Taylor says in a new lawsuit she relied on the promise she'd get fuller, silkier hair.

So imagine her dismay when she looked in the mirror to see bald spots, burns, blistering and scabs on her scalp ... this according to legal docs obtained by TMZ.

We broke the story ... L'Oréal was sued back in September when a group of angry customers made similar allegations ... this after L'Oréal got a bunch of celebrities to tout the product.

Johnny Rotten made the Sex Pistols punk rock pioneers, and was frequently covered in bodily fluids while he did it ... but that was the 70s.

Johnny's trademark spiky hair -- and just about everything else about him -- has made a huge transformation in 2016.

Fetty Wap's latest grill doesn't have a single piece of bling in it, but it's brighter than anything else he's rocked -- as it should be ... since he paid about $4,000 per tooth to get it done!

TMZ has learned Fetty hit up Dr. Mojgan Fajiram of Sutton Advanced Cosmetic Dentistry in NYC recently, looking to score the straightest, whitest looking teeth possible. The doc's office says they hooked Fetty up with 20 porcelain veneers, top and bottom.

Fetty's rep tells us, all told, he was in for $80k once the 2-step process wrapped last week. Not quite a million dollar smile, but he seems satisfied.

Don't know how we missed this ... but did you know Chesley "Sully" Sullenberger -- HERO of Flight 1549 -- SHAVED HIS MUSTACHE?!?!

Sully is featured in a new commercial for St. Jude Children's Research Hospital (#hero) -- when we realized he's chopped off his signature lip warmer.

Don't get us wrong, he still looks great but we gotta ask ...
