About This Shade
Garnier Nutrisse Ultra Color B4, Golden Mahogany Brown (Caramel Chocolate), is a creamy, chocolatey brown with intense caramel reflects.
Is This Shade Right For Me?
B4 is best for anyone with natural hair between dark blonde and darkest brown. For a different brown shade in the Ultra Color range, check out B3 Golden Brown (Spiced Rum).
For those who currently have color-treated hair, there are special considerations for the color result you can achieve. Because of this, we do not recommend B4 for hair that has been previously colored medium brown or darker. We also do not recommend using this shade on hair that has previously been relaxed, bleached, or highlighted. For more help, use our Shade Selector Tool to find the shade for you!

How to Apply Nutrisse Ultra Color
Step 1: Allergy Test
48 hours before each use of the product, complete an allergy alert test, even if you have used hair color products before.
Step 2: Preparation
Place a towel around your shoulders, remove any jewelry, and put on the gloves. Open the color crème tube and screw the cap back on completely to pierce the tube.
Step 3: Combine
Squeeze the entire contents of the ampoule and color crème tube into the applicator bottle.
Step 4: Shake
Shake the mixture for 30 seconds to mix evenly. Break off the tip of the applicator to start applying. Use immediately after mixing. Do not store mixed color.
Application Option 1: Full Head
Leave the formula on your hair for 30 minutes, or 35 minutes if you have a lot of grays.
Apply through the lengths and ends and massage well into your hair to evenly spread the colorant.
Leave the formula on your hair for 30 minutes, or 35 minutes if you have a lot of grays.
Application Option 2: Root Retouch
Begin with your roots by using the bottle to separate the hair section by section and applying the colorant. Leave the formula on your hair roots for 20 minutes, or 25 minutes if you have a lot of grays.
After the time has passed, apply the formula through the lengths and ends of your hair. Massage well to ensure the colorant is evenly spread. Leave the formula on your hair for an additional 5-10 minutes. Blend well where new growth meets previously colored hair to avoid banding.
Don't Forget to Rinse & Condition!
Whether applying Nutrisse Ultra Color on your full head or for a Root Retouch, your final step should always be to rinse and condition.
Apply water to your hair and gently massage to emulsify the colorant. Rinse thoroughly until the water runs clear. Apply the silicone-free conditioner and leave on for 2-3 minutes.
Rinse thoroughly and dry your hair. Style your hair the way you like it and admire your new radiant look.

only dyed my roots
Izzy552
13 years ago
I purchased the Nutrisse Ultra Color B3 Golden Brown for my very dark hair. According to the box it would make my dark hair much lighter. I had dyed my hair nearly black (by accident) months ago and finally decided it was time to go back to my natural light brown hair color.
I followed the instructions and after rinsing out my hair and towel drying it I noticed that my roots were extremely light (the exact color on the box) but the rest of my hair was STILL DARK!
Now my hair looks really ugly and I will have to dye my entire head dark again :( I don't have money to be wasting on the salon and I was hoping that this product would lighten my hair.
I wouldn't waste time buying this product again. If you have dark hair and want it lighter I suggest saving your money and going to a professional. This hair dye does NOT do it's job. I'm very disappointed...

Didn't Color my Hair
2 months ago
I dyed my hair today with this product, B4 that I purchased in May 2025. I noticed it became very thick in the bottle after mixing it. I had to shake it several times to get it to come out. Maybe that was my warning that something was wrong. I put it on my hair and left it on 30 minutes. After rinsing it out, I noticed it barely colored my hair, and the gray was still showing. Kind of a dull color on my hair. I looked for an expiration date, but I didn't see one, only 70Z100.
No, I do not recommend this product.

Not good for grey roots for me
7 months ago
Did not cover my grey and I purchased two boxes to do my whole head. Very disappointed . My go to is 535 and I wanted a change. Out money and disappointed. Left it on roots first and then produced to color rest of hair. It’s not that golden color . It’s a mousy color. I even checked to see it was in the same family as 535. Worse part $12.99 x2. Plus add tax on top. Plus cap was off on one of the colors . Love 535 not B4
No, I do not recommend this product.

Disappointed
11 months ago
I used this on my natural dark brown (nearly black) hair and it barely made a difference. I have long hair and used 2 boxes but it only made my hair maybe a half a shade (if even) lighter. Nowhere near the color advertised on the box. Waste of money.
No, I do not recommend this product.

First of all, most of the time I buy hair color only if they are on sale regardless of how is going to turns out…I don’t enjoy it Matchi Matchi nor perfections when it comes to colors.’’who cares?… it’s my hair my choice…showing it off is fun… I also get complements…. Unlike the rest of people, I have a uniquely way of liking things. Explanation: I never use the same color as the one I previously used. Example of my last experience’ RZ4
( intense bronze red) Oh! a bit red. Last night I colored the roots with GARNIER Nutrisse B3 (Golden brown) I Love It… this is the first time in my life I am ordering the B3 for next time…❤️. The only thing it’s higher price online.’ I may only get it if I can’t find it on sele. Hunts begins now…
It made my roots orange/red. Very disappointed in the color because it didn't properly color the ends so it's giving reverse ombre. Not the vibe I was going for. I wanted a shade or two lighter color with the dimensions.
No, I do not recommend this product.

A: Hi bobbbbyyyy123! Thank you for your interest in Nutrisse Ultra color, B4-Golden Mahogany Brown/Caramel Chocolate. This shade is exclusively for dark, brunette hair. Not all hair type lightens easily. We would recommend a strand test you view your result. Virgin hair, thick hair, and hair longer than neck length will require 2 kits for first time application. This shade was used on natural Medium Brown hair to achieve the color result on the front of the box.

Q: Would this color work on blonde…. I love the shade but I see it’s meant to brighten darker shades to this color. Is there a similar color I could try if I want to go from blonde to this shade?
A: Hi, Lo47, Thanks for reaching out! HL1 Bright Toffee is not recommended for blondes. We suggest trying Nutrisse #63 Light Golden Brown, which can be used on blonde hair. We also suggest doing a strand test to preview your results. Thanks for your interest in Garnier!

Q: I usually use Acorn #60 to color my hair. It covers my grays, but I would like to go a little lighter. Can I do this with Bright Toffee HL1?
A: Hi there Gin71! The Nutrisse Ultra Color HL1, ""Bright Toffee"" was specially designed for women with the darkest natural hair who are looking for dramatic lift. It can lift up to 4 levels without bleach and creates a rich, bronze result. HL1 is for you if you begin with naturally black to medium brown hair. However, if you need to cover gray hair, a high lift color like this won’t give you any gray coverage. To go one shade lighter than Nutrisse acorn # 60, use the dark blonde # 70 for your next touch up. This color is one shade lighter and will cover the gray.

Q: I was expecting a nice golden brown color and what I got was horrible!!! My hair is poop brown and I’m embarrassed to let anyone see me !!! What can I do to fix this disaster???
A: Hi there! We wish you were able to see the results you were hoping for with the Nurisse Ultra Color B3 - Golden Brown. This shade B3 is designed to lighten up to 3 levels without bleach. This shade has ultra reflective golden tones that will leave you with a warm result. It is best for anyone with natural hair between medium brown and black. This shade is specially made for use on dark hair, because of this, we do not recommend shade B3 for hair that has been previously bleached, highlighted, hair that is predominantly gray, or if you have previously colored your hair medium brown or darker. If its too golden, add more natural brown to the hair and use a light natural brown 60 or medium natural brown 50 in Nutrisse.
