The $8 Treatment That Helped My Hair Finally Grow Past My Shoulders
Two years ago I had a little heart-to-heart with my bathroom mirror.My hair was fried. Snapping. Shedding. Refusing to grow past my shoulders like it had signed some invisible lease there. Years of bleach and dye had officially caught up to me, so I quit cold turkey and went into full “hair rehab era.”That’s when I found Soapbox.Their shampoo and conditioner already saved my ends from feeling like straw, so when I saw this “Oh My Growth” vitamin booster treatment, I figured… why not. Worst case, it smells nice and I pretend I’m doing something productive.Turns out, it actually does something.The texture surprised me first. It’s super lightweight. Almost like water or a skincare essence, not a heavy cream. I was expecting something thick and greasy, but this feels feather-light. No oiliness, no coating, no “why does my head feel like I deep-fried it?”After shampooing, I mix a little into my conditioner or hair mask and let it sit for about 10 to 15 minutes while I do the rest of my shower routine. Rinse, done.No drama. No complicated steps.Over time though, the difference has been kind of wild.My hair finally started… growing. Like actually growing. For the first time in forever, it made it past my shoulders and now sits just past the middle of my back. I remember catching my reflection one day and thinking, “Wait… when did you get long?”It looks fuller, shinier, and has that healthy bounce I haven’t seen since my early 20s. My split ends look calmer, my shedding is way less, and there’s noticeably less hair in my brush after styling. That alone sold me.And because it’s so lightweight, it never weighs my hair down or makes it flat. It just feels clean and healthy.For $8, it honestly feels like a steal. I’ve paid triple that for products that did absolutely nothing but smell expensive. This one quietly works in the background and just lets your hair do its thing.If you’re trying to grow your hair out or recover from a few questionable color decisions (been there), this feels like a really easy, low-effort addition that actually pays off.My hair finally feels like it’s cooperating instead of fighting me.We’re on speaking terms again.

A must have!
I wish I could give more stars, I am truly blown away by this product. I gave myself a terrible bob (just below ear length) October 2025 and was desperate for some relief. I purchased this bottle in the beginning of February 2026 and my hair has not only grown in inches (at least 2-3 inches since using) but in thickness as well. I’ve attached pictures of all my new hair growing in. My hair is the healthiest it’s ever been- and I’ve done nothing different except use the Oh My Growth. I still box dye my hair and use light heat every few days. I only wash my hair once every 5-7 days- meaning I only use this product that often, and I still have incredible results. It also smells amazing! I will continue to purchase over and over!

Love this stuff!
I am a bit of a hair product junky. I have tried numerous products to help my thinning, breaking, frizzy hair. I’ve now used this 5 times and I’m amazed! Not only does my hair look a little thicker and fuller, but it has tamed my frizzies better than any product I have tried. My hair is manageable for the first time in a long time.

SMELLS DIVINE
Beyond the effectiveness of this product, I would use it if it didn’t make my hair feel fuller and healthier for the smell alone. I can’t tell you if it works for growth yet but I will buy this forever because of the subtle, fresh, clean smell it leaves behind for days. I have a super sensitive nose to people’s odors in particular. I can smell if someone drank alcohol the day before by just standing in the same room and not smelling their breath. There’s a certain sour smell. Got a little off subject but the point is, I’m overly aware of any body smell and because of that, I’m overly self conscious that my fresh washed hair could smell like that and I have literally never had oily hair in my life. I have super dry curly hair. Odd thing to be worried about but hey, we’re humans and unreasonable sometimes.Now that I’ve been an oversharer, back to the product.I originally bought it to help my 10 year old who also has super curly hair but struggling to grow it on the top, get that moving. I’m hoping it helps with her growth but I will also use it for the smell on mine. Time will tell.

Result
I have been using for a couple weeks now. I haven’t noticed any growth, but it does make my hair smell nice.

Actually works
It’s only $8 and genuinely works. I do three stripes of it – down my middle part and sides before I condition, massage it in and rinse it out after 5-10 minutes. My hair is growing so fast it’s almost annoying how much I have to touch up my blonde roots and my hair stylist made a comment today on how healthy my hair feels. This is a RINSE OUT treatment, follow the directions for real results 😀
