Frizz doesn’t stand a chance against the strong hold and curl-activating properties of this silicone-free styling concentrate. Our natural formula not only resists humidity, but is reactivated by sweat and water, making this essential for frizz-prone curly and wavy hair.  Shine-enhancing botanicals, plant-derived proteins, and penetrating humectants deliver multi-day hair that can withstand the elements.   So put your hands in the hair and keep those curls where we can see them – this is a Hold Up™!

A silicone-free curl defining serum that softens and strengthens hair while offering strong hold and curl activation.

Fine to thick ‘wavys’ and ‘curlys’ who seek curl plumping, lift, and strong hold.

Quinoa Protein is a gluten-free source of eight essential acids that offer superior repair, hydration, and shine for the hair. Oat Protein plays a supporting role by penetrating the hair to deliver reduced breakage and enhanced softness. Click for a full list of ingredients.

Cucumber Mint.

Rake a small amount of serum through wet hair from roots to tips. (Note: we call it a ‘concentrate’ for a reason - a little goes a long way). To accentuate vertical lift, flip hair upside down and smooth product downwards, working from the crown to the ends of your hair. Allow hair to air dry or blow dry for extra volume.

To enhance in your natural curl pattern, apply Hold Up™ to wet, not damp, hair. Once you have achieved your desired style, avoid manipulating your hair until it is fully dry.

Because this product works by forming a film on the outside of the hair, we do not recommend it for low-porosity, tightly curled hair as this may lead to flaking and dullness. Instead, we recommend Just Gel™, which is non-flaking, softens hair and provides moderate hold.

  1. amazing hold

    Posted by Joanne Salegna on 21st Aug 2019

    Hold Up serum has amazing hold and creates a great cast after diffusing. Once my hair is completely dry, I scrunch out the cast and I’m left with beautiful curls with amazing hold. I use about 3 quarter size amounts for my entire head which is raked in.

    Superior hold and frizz control.

  2. #1 styling product for lasting curl

    Posted by Laurel on 1st May 2019

    This is the easiest wash and wear styling product ever. It lasts for up to 3 days with a splash of water added the next morning. There is no color problem with this clear gel and gray/silver hair.

  3. wonderful

    I love all of you products.

  4. Amazing

    Posted by Shallette Pope on 13th Oct 2017

    This product is amazing! It holds my curls until the next washing. I love this product!

  5. Hold Up holds up!

    Posted by Unknown on 25th Sep 2017

    I love this stuff! I bought Hold Up based on other reviews, but had difficulty with it out of the gate. Thanks to Rachel's guidance, I started cocktailing OMG with Shape Shifter, and then locked it all in with Hold Up. Nirvana!!! I get three solid days and a 4th fair-to-middling day with this combination on my 2C, fine, transitioning-to-silver hair. Wonderful!

  6. outstanding

    Posted by Unknown on 14th Jun 2017

    This serum has incredible hold. It has the best hold of any product I've used in twenty years, without the crunch, white flakes, and chemicals of the gels I used to use.

  7. Makes low maintenance hair look good

    Posted by Laurel on 6th Dec 2016

    A small dab of this and my moderately curly hair stays presentable all day. I rub it through my towel dried hair after a shower and crunch it up a bit in a few spots. After it has dried, my hair only needs a bit of light brushing to smooth the sides a bit. There is no flaking or stiffness that other products for the same purpose might produce.

    I absolutely love this product! It's a staple for me (along with the shape shifter). My hair is 3a/b and this product is just fantastic. I use this as my final product when styling my hair. It gives me extra hold which helps me have 2nd and 3rd day hair. It also gives me shine. I will repurchase again and again. I don't have to use much, maybe a quarter size puddle for my long hair. The small bottle will last me quite a while. I bought the medium sized bottle recently and plan on buying the liter size when it's back in stock. I use this every time I style. Thank you for a fantastic product! Please don't ever change the formula or stop making this wonderful product.

  9. LOVE IT

    Posted by Jessica Hudson on 23rd Nov 2015

    Hold up Defining Serum: I just bought this product a week ago & I absolutely love it. The only other product I have used from Original Moxie is the Just Gel. I cannot get enough of that product either. I have thick, dry kinky curly hair. Today I am wearing day 3 hair and it still is curly and defined. The only thing that I might suggest is different scents. I am not a huge fan of the smell, but it is light. I will definitely deal with the smell for the way the product works! LOVE IT!

  10. The best for no frizz!

    Posted by Jo on 20th Jul 2015

    I have very fine, curly hair that is extremely dry and as a result very frizzy. Original Moxie products have completely changed this.

    I use Hold Up on wet hair after OMG and Shape Shifter to seal my curls and form a cast whilst my hair dries. This keeps all the moisture in and once dry, I comb my hair to break the cast and have lovely soft bouncy curls.

    I have medium length hair and only use an amount the size of a 10 pence piece (not sure of a US equivalent, sorry from Scotland but it isn't much at all). If I still find my hair is a little fluffy I use a tiny amount of Mane Tame which just melts into my hair beautifully!

    I have also tried Just Gel and find Hold Up to be much better for my hair. If in doubt try the mini's, it's trial and error to start but it's 100% worth it.
