Benefits of the Blue Essentiel Do-it-all Brush
Complete hair care
The boar bristles in this hairbrush offer complete care for your hair. Rich in keratin, boar bristles naturally moisturize your hair from root to tip, smoothing the hair cuticles to provide instant shine!
The nylon fibers are carefully designed to allow them to work through the hair and effectively detangle from root to tip. The Blue Essential is the perfect hairbrush for detangling even the most stubborn hair.
How to use
Suitable for all hair types, the Blue Essential Do-it-all brush is perfect for detangling and styling. In the evening, use it to rid the hair of impurities and nourish it before bed. It is also great for touch-ups during the day and fits perfectly in your handbag.
For the finest hair and most sensitive scalps, choose the N.03 Essential Soft Hairbrush.
Preferably, use the Blue Essential Do-it-all Brush on dry or damp hair to benefit from the unique properties of boar bristles and nylon fibers.
Materials
The mixed composition of the Blue Essential Do-it-all Brush makes it the perfect styling tool! The mixture of 100% keratin boar bristles – an exact mirror of your hair's structure – and unique nylon fibers allow you to detangle the hair and stimulate the scalp.
Boar bristles and nylon fibers are hand-placed on an ultra-flexible rubber base to ensure optimal bounce when styling: the most revitalizing beauty routine for your scalp.
Efficacy
We have carefully designed the stiffness of the nylon fibers and the flexibility of the rubber base so it provides a deep massage that stimulates the scalp's blood circulation and hair growth.
The Blue Essential is ideal for everyday brushing, as it takes care of your hair while detangling it. The perfecting tool par excellence for any moment of the day, it stimulates your scalp while bringing softness and moisture to your hair!
Pro tips
If you've never used this type of brush before, don't be surprised: its deep massage is quite intense and takes some getting used to. Those with more sensitive scalps may want to opt for The Essential Do-it-all Brush.

Reviews
My Favorite Beauty Purchase This Year
"I honestly didn't expect to love a hairbrush this much, but this has become one of my favorite beauty purchases. Not only did I buy one for myself, but I also bought two of the smaller brushes to keep in my handbag and office, one for each of my daughters, one for my mom, and one for my sister. That's probably the highest compliment I can give a product. Within a short time, my hair already feels shinier, smoother, and silkier. The brush glides effortlessly through my thick hair without pulling, and it leaves my hair looking polished instead of frizzy. More than anything, using it feels like a small act of self-care. Taking five minutes to brush my hair has become a little luxury that I genuinely look forward to each day. It's one of those products that elevates an ordinary routine into something that feels special. If you've been debating whether it's worth the investment, I can honestly say it has been for me. I would buy it again without hesitation, and clearly I already have!"

Absolutely changed my hair!
"Who knew that a hair brush can improve your hair health? La Bonne Brosse do and I must say, my hair is shinier and the frizz has decreased. I was very self indulgent and purchased two!! The numbers 02 and 07. They are such good quality. I need to invest in the matching pouches now so I can take them everywhere with me! Well done Team 👏 ✔️"
— Jill C. (5/5)
Tough little brush
"It's is hard to find quality brushes that are smaller size. My hair can get out of control very easy so I always carry a brush. This brush has strong bristles yet does not pull on my hair. The size is perfect to keep in my purses."
— Amy M. (5/5)
Beautiful Brush!
"So I hesitated to buy the #2 brush and matching case. . . . would they be worth the cost?? But when free shipping kicked in along with a free cleaning brush as part of a Memorial Day sale, I couldn't resist! And I'm oh so glad I didn't!! This brush is EVERYTHING! I have naturally curly, thick hair which tends to tangle; I have also been experiencing some hair loss with washing/conditioning. Since using this little miracle brush, the hair loss has been greatly reduced! My hair is shinier and my scalp is happy that it's being tended to! If you're hesitating, don't! You won't regret this purchase!!"
— Kippi K. (5/5)
Mostly love at first brush
"I really like the #2 brush for regular brushing and smoothing. It does not go deep enough into my hair/scalp for styling. I will need to get a 2nd brush to help with that. I do like how smooth and healthy my hair feels after using the brush daily."
— Amber A. (4/5)
Luxury Haircare at Its Finest
"I absolutely adore the La Bonne Brosse No. 2 brush in Essential Pink. There is truly nothing I don’t love or appreciate about this brush. From the stunning design to the incredible quality and performance, everything about it feels luxurious and thoughtfully made. It glides through my hair effortlessly, feels gentle on my scalp, and leaves my hair looking smooth, healthy, and polished. The Essential Pink color is also so chic and beautiful. This brush has completely elevated my haircare routine and feels like such a special everyday luxury. I can honestly say it is amazing in every way."
— Heather W. (5/5)
Yes! Worth it!
"This is my second la bonne brosse brush and I much prefer this #2 to the all boars head version I purchased several years ago because I have long hair and the #2 moves through my hair easier and actually reaches my scalp. Also worth it—buy the pouch! It looks like a cute sleeping bag for your brush. And then add the brush cleaner which is very effective. If you are paying for the brush, just go all in!"
— Carol S. (5/5)
Wunderbare Bürste
"Ich hätte nicht gedacht, dass ich mich auf das Haarebürsten so freuen kann. Es ist ein schönes Ritual geworden und ich habe das Gefühl, mir etwas Gutes zu tun. Die Bürste fühlt sich wunderbar an - sowohl in der Hand, als auch auf dem Kopf. Die anfängliche statische Aufladung der Haare tritt nicht mehr auf. Ich habe viel Freude an dieser Bürste. Warum habe ich sie erst jetzt entdeckt?"
— Elke R. (5/5)
CANNOT BELIEVE THIS HAIR BRUSH
"I cant believe how much I love my new hair brush. Originally, I bought the smaller size to keep in my purse, but one week later I bought another except the full size. One brushing and I felt a difference in my hair. It allows my blowouts to last longer, less flakes and I loose much less hair overall. Im BLOWN AWAY by the product. I cant believe I spent that much money but now I cant believe I went so long without it."
— Anne G. (5/5)
No. 2 perfection
"This brush makes my hair feel so silky soft. It feels relaxing to massage my scalp too :) A delight!"
— Annie S. (5/5)
