ByErim products are wonderful
ByErim products are wonderful, I have been using them a good few months, and my hair has improved so much, my hair loss is less, my hair looks and feels healthy after so many years.
I would definitely recommend ByErim products and I will carry on using them.

Hi Jasminder,
This is so wonderful to hear and honestly brought a tear to our eye 🖤 Thank you for sharing your journey with us, knowing that your hair loss has reduced and that your hair feels healthy after so many years means more to us than words can express.
That's exactly why ByErim exists, to make a real, lasting difference. You deserve every bit of this progress!
Thank you for recommending us and for continuing to be part of our community. We're rooting for you every step of the way x
Best hair oil i've come across
I have been using ByErim hair oil on my daughters’ hair for the past few years and have observed excellent results. Their hair has become noticeably thicker and longer over time. The oil has a pleasant fragrance and, unlike many alternatives, is not excessively greasy. I typically apply it immediately after washing their hair, and it consistently leaves their hair feeling soft, smooth, and visibly shiny.

Hi Aman, this made us smile so much 🖤 Thank you for trusting ByErim with your daughters' hair over the years, that is truly the greatest compliment we could receive as a brand.
Thicker, longer, softer and shinier hair over time is exactly what we set out to achieve, and hearing that it's working for your little ones means everything to us. We love that it's become part of your post-wash routine, it really is the perfect moment to apply!
Thank you for being such a loyal part of the ByErim family. Wishing your daughters continued hair growth and health x
Great product, bottle could be more functional
Absolutely no complaints about the product, i'm a repeat buyer for a reason!
The only thing i would say (whilst on my 6th oil bottle) is how i wish there was a way to see exactly how much product was left inside - it's a weighty bottle so it can be hard to gauge! If not an entirely clear bottle then maybe a clear strip going down the side to allow some visibility?
Love the brand, the owner and what it/she stands for 🫶🏽

Hi Rumana,
6 bottles in? you are an absolute legend and we are so grateful for your loyalty 🖤 Thank you for being such a consistent part of the ByErim family!
And thank you for this feedback, honestly, this is exactly the kind of insight we love to hear. You're not the first to mention this and it's something we're genuinely taking note of. A visibility strip or clearer design is such a practical idea and we'll be keeping this in mind as we continue to evolve the packaging.
Your support means so much, not just as a customer but as someone who takes the time to share thoughtful feedback that helps us grow. We see you and we appreciate you more than you know 🫶🏽

I will never stop using ByErim
I will never stop using ByErim for as long as they keep creating their amazing products. I’ve been using the hair oil ever since it first came out and keep adding to my collection with every release! Never been disappointed and the compliments on my hair keep coming. Can never go wrong with ByErim. Highly recommend to everyone

Hi Afareen,
From day one? that means everything to us 🖤 Thank you for growing with ByErim and for being part of this journey from the very beginning. Knowing you've been with us since the start and that every new release has found a place in your collection… we genuinely couldn't ask for more.
And those compliments on your hair? You've earned every single one! Comments like yours are what keep us going and pushing to create products we're truly proud of. We promise we won't stop, so neither should you! Thank you for always recommending us, it means the world. Here's to many more releases together 🖤
I’ve tried every single product ByErim…
I’ve tried every single product ByErim offers (minus the new drop) and everything does what it says on the tin! The hair oil has helped my hair growth so much. I’ve used it consistently for 6 months + (twice a week) and my hair is fuller and healthier. This hair oil really is a game changer for me. So much so, friends and relatives have asked what I used and I direct them here. I used to use coconut oil and Amal oil religiously but honestly they didn’t make much of an impact as byerim’s hair oil did for me.
My favourite product has to be the hair mist! I can’t finish getting ready without it. There aren’t many nice hair mists in the market but this one gives me so many compliments it’s unreal. Both oudrose and cedarsmoke are truly beautiful scents. I literally have to hide them from my sisters so they don’t steal it!

We are OBSESSED with this review 🖤 Thank you so much for taking the time to share your experience, this truly means the world to us. 6 months of consistent use and visibly fuller, healthier hair? That's exactly the kind of transformation we pour our hearts into creating.
And the fact that you're sending friends and family our way is the biggest compliment we could ever receive, welcome to the ByErim family, everyone!
Now the hair mist… we completely understand the sister situation 😄 Oudrose and Cedarsmoke are two of our absolute favourites too , we couldn't choose either! You may need to invest in a second bottle (or a very good hiding spot).
Thank you for being such a loyal supporter, we can't wait for you to try the new drop!
INSANE OIL
I am genuinely impressed with the quality of this oil. Finding a product that balances deep nourishment with a clean finish is rare, but ByErim has absolutely nailed it.
Performance & Texture
The consistency is rich and luxurious, yet it defies the common pitfall of many oils: it leaves zero greasy residue. My hair feels significantly softer, and my beard—which is typically quite coarse—is much more manageable and hydrated.
Skin-Friendly & Natural
As someone prone to acne breakouts, I am usually hesitant with new oils. However, this formula is incredibly lightweight on the skin; it doesn't feel heavy or "clogged," and I’ve experienced no irritation or breakouts since I started using it. The scent is another highlight—it’s wonderfully natural and subtle, avoiding that synthetic, over-perfumed smell found in cheaper alternatives.
The Verdict
Knowing it is Dermatologically Approved and Clinically Tested gives me total peace of mind. It’s a versatile, high-performing product that delivers on every claim. I’m already looking forward to trying the Cedar scent next!

WOW, "Insane Oil" is officially our new favourite title! 🖤 Thank you so much for this incredibly detailed and thoughtful review, it genuinely means everything to us.
The fact that it's working for both your hair AND your beard, with zero greasiness and no breakouts, that's exactly the versatility we designed this for. We know how cautious you have to be when you're acne-prone, so hearing the formula feels lightweight and clean on your skin is such a relief and a joy to read.
You've perfectly captured what sets ByErim apart , that balance of deep nourishment without the heavy, synthetic feel. The dermatological approval and clinical testing exist precisely for customers like you, so you can use it with complete confidence. 🖤
And yes ofcourse, the Cedar scent is waiting for you and we have a feeling you're going to love it just as much! Can't wait to hear what you think. 🖤✨

A couple things
A couple things: I don’t typically write reviews even when I’m satisfied and I’ve also invested in a number of other hair oils.
That being said, I always incorporate ByErim hair oil into my hair routine regardless of venturing to other products — it is my go-to and cannot be replaced. I use it everyday because it doesn’t build on the hair and it’s so nourishing. I love it.
I have my hair oil on subscription and I noticed it had been a month since my last tracking update. I was unable to get a response or any further information from the tracking company. However, I reached out to the ByErim team and they replaced my order quickly with no charge. I really appreciated this. I’m a loyal customer and I would’ve paid again because her product is so well made. It was such a sweet surprise to see that it was taken care of and it made me feel valued as a customer.
Thank you again, ByErim<3

Hi Gina,
This has genuinely moved us, thank you so much for taking the time to write this, especially knowing you don't typically leave reviews. That means more to us than you know. 🖤
The fact that ByErim is your non-negotiable, go-to oil regardless of everything else you've tried is the highest compliment we could ever receive. Knowing it works for you every single day without buildup and keeps your hair nourished is exactly why we pour so much care into every bottle.
And as for the lost parcel, aw you are a loyal, valued customer and there was absolutely no question about making it right. The fact that you said you would've paid again genuinely touched our hearts. You deserve to feel taken care of, always. 🖤
Thank you for being part of this journey with us. Customers like you are the reason we do what we do. Here's to many more years together! 🖤✨

I’ve been using this hair oil…
I’ve been using this hair oil consistently since last year February as part of my hair growth journey and it’s honestly one of the best I’ve tried. It’s lightweight, doesn’t feel greasy, and has made my hair feel noticeably softer and healthier. I’ve also seen less breakage and more shine over time. You can tell it’s been made with real care and definitely a staple in my routine now.

Hey Muhammah,
Wow, a full year of using our hair oil, we're so honored to be part of your hair growth journey and to hear it's making such a real difference for you.
The softer feel, less breakage, and that shine? That's exactly what we're going for, and hearing it's actually working for you means everything to us. You're so right about the care that goes into every bottle , we're a bit obsessive about getting it just right, so knowing you can feel that makes us ridiculously happy.
Thank you for sticking with us and for taking the time to share this. Here's to many more good hair days ahead! 🖤✨

My Experience with Erim
I visited the ByErim stand at Westfield Stratford on Friday, which would’ve been one of the busiest days of the year (boxing day) but I was so lucky to be able to meet and get served by Erim herself. I was so honoured to be able to meet her finally in person and can I just say she is actually the loveliest person and so beautiful inside and out. I was so shy to begin with, as if I was speaking to someone famous (which she is) but she made me and my sister feel so comfortable within seconds - literally as if I’ve known her all my life. Absolutely love people who are like that. She kindly did a quick hair/scalp analysis and took her time to show us all her lovely products. I purchased the hair perfume to add to my collection and tried it on for the first time out today. Smells absolutely divine and I’m not even exaggerating. All of ByErim products are a 10/10 I’ve literally been purchasing off her website since it launched and there’s no going back. It’s so lovely and refreshing to meet down to earth and heart-warming successful south Asians and Erim really is one of them. She gave me such a warm hug I had to go home and tell my whole family about how lovely the overall experience was, she made my day ♥️

Hi Sharmin,
Awww, stop, you're going to make us cry! 😭🖤 Boxing Day at Westfield was absolutely mad, so the fact that you got to meet Erim in the chaos makes this even more special. She's going to be so touched reading this, the "famous but makes you feel like family" vibe is exactly who she is, and we're so glad that came through even when you were feeling shy at first!
The hair analysis, the perfume, the hug, this whole experience sounds like the best kind of day. And you've been with us since launch?! That's incredible loyalty, and we genuinely appreciate you sticking with ByErim through it all. Thank you for sharing this with your family and for taking the time to write something so beautiful. You made OUR day! ♥️🖤 x
