Fact or Myth?

Does Dirty Hair Grow Faster?

The Verdict: MYTH

You've probably heard it before: "Don't wash your hair too often—dirty hair grows faster."

It's one of the most common hair myths, but the truth is that hair growth begins beneath the scalp inside the hair follicle. Whether your hair is freshly washed or a few days between cleanses doesn't determine how quickly it grows.

Why This Myth Exists

Your scalp naturally produces sebum, an oil that helps protect and condition your hair. Because clean hair can sometimes feel lighter or appear less full, many people assume leaving it unwashed encourages faster growth.

In reality, natural oils help condition the hair—but buildup itself doesn't increase hair growth.

A Healthy Scalp Matters

The goal isn't to keep your hair dirty.

The goal isn't to wash it every day.

The goal is to maintain a healthy, balanced scalp that works for your hair type and lifestyle.

A thoughtful cleansing routine can help remove excess oil, styling products, sweat, and buildup while supporting your overall haircare routine.

The Botanical Perspective

At Unique Organics, we believe healthy hair begins with intentional scalp care.

That's why our botanical philosophy focuses on gentle cleansing, nourishing ingredients, and consistent rituals inspired by nature.

The Verdict

MYTH

Dirty hair does not grow faster.

Healthy hair starts with a healthy scalp—not outdated myths.

Change in volume?

I've been using this product since 8/1/2023. If you don't believe me, go on Etsy and see the review I left there of my side by side comparison just after a few months. I absolutely love the product and since then, with the help of "Curry up and Grow", I've been able to achieve hair goals, such as Sisterlocks and feel confident having them. The oil was used as directed from the Etsy posting and I've achieved thickness, as well as length. I understand that the products are hand made and may seem a little different from time to time. However, I couldn't help but notice that the bottles are becoming slightly smaller every time I order and this time the oil had a much looser consistency. I didn't mind the lemon sent as much, however I more so enjoyed the sweet smell if the previous batches a lot better. It was almost like applying a subtle perfume to my hair but still allowing it to grow. I'm just not a fan of the lemon smell. That still won't stop me from recommending your product to anyone who's looking for hair growth. I've been with my loctician for almost 2 years and she sees the growth within my hair, as well as her own. At times she'll even recommend it to her clients. All in all, it's been a wonderful and reliable product and I really hope it continues to be just that! Thank you for helping me reach my hair goals! I'm writing this review (which I don't do often), to show anyone who's in disbelief. Sorry, I'm unable to rearrange the picture order.

Thank you so much for this beautiful and thoughtful review. It truly means so much to know that Curry Up and Grow has been a part of your hair journey since 2023 and has helped you reach your goals with your Sisterlocks. I’m so happy to hear that both you and your loctician have noticed the growth, thickness, and length.

I also want to reassure you that the bottle size has not changed. Curry Up and Grow has been packaged in the same size bottle for the past 6 years. Since each batch is handcrafted with real herbs, oils, and botanicals, the scent, color, and texture may vary slightly from batch to batch depending on the natural ingredients used. I truly appreciate your honest feedback about the lemongrass scent. For future orders, you are more than welcome to contact me before placing your order so I can customize the fragrance option for you when available. I always want you to love your ritual from start to finish.

Thank you again for your continued support, your recommendations, and for trusting my products with your hair journey. I’m so grateful to have you as a customer.

Some relief

Have only been using for a few weeks. Noticeable improvement in burning scalp sensation. Too soon to see new hair growth.
The melatonin spray is also very comforting for itching and burning scalp.

Absolutely greatness

I am so happy to state on my health hair journey this oil is fabulous. I warm it sometimes or just add to water herbs and all I work it through my hair and do a soft scalp massage. It smells and feels so good. A little goes a long way but I will be making another purchase of this oil. I have little hairs just sprouting where it used to be mean and clean around the hairline also my crown is crown’in. I truly recommend adding or making your first purchase you will be happy.

Melatonin overnight hair oil

I’m glad I gave this a chance because I have after 2.5 weeks crown sprouts and my entire hairline is growing back in I use a few other products from here for a complete line. It’s smells like chocolate and licorice, a little goes a long way. I use only twice a week because of my job but I sit under the dryer to ensure maximum benefit. I highly recommend as with everything consistency is key and patience.
