How to Use Olaplex No.4 Shampoo and No.5 Conditioner for Healthier Hair

 

If your hair is dry, damaged, color-treated, or prone to breakage, Olaplex No.4 Bond Maintenance Shampoo and Olaplex No.5 Bond Maintenance Conditioner are designed to help repair and strengthen it. These products work by rebuilding broken bonds in the hair caused by heat styling, coloring, and environmental damage.

Using them correctly helps you get the best results. Here is a simple step-by-step guide.

Step 1: Thoroughly Wet Your Hair

Start by fully saturating your hair with warm water. Warm water helps open the hair cuticle slightly so the shampoo can cleanse effectively.

Make sure the scalp and the full length of your hair are completely wet before applying shampoo.

Step 2: Apply a Small Amount of Olaplex No.4 Shampoo

Olaplex No.4 is highly concentrated, so a small amount is usually enough.

  1. Dispense a dime- to quarter-sized amount into your palm.

  2. Rub your hands together to distribute the product.

  3. Apply mainly to the scalp and roots.

Focus on massaging the scalp with your fingertips to lift oil, dirt, and product buildup.

Step 3: Work the Lather Through the Lengths

Once the shampoo begins to lather at the scalp, gently work the foam through the mid-lengths and ends of your hair.

Avoid aggressively scrubbing the ends since they are the most fragile part of the hair.

Step 4: Rinse Thoroughly

Rinse your hair completely with warm water until no shampoo remains. Leaving residue can make hair feel heavy or dull.

If your hair is very oily or has a lot of product buildup, you may repeat the shampoo step.

Step 5: Apply Olaplex No.5 Conditioner

After rinsing out the shampoo:

  1. Squeeze excess water from your hair.

  2. Apply a small amount of conditioner to your hands.

  3. Work the conditioner through the mid-lengths and ends.

Avoid applying large amounts directly to the scalp, especially if your hair is fine or tends to get oily.

Step 6: Let It Sit for Maximum Repair

Leave the conditioner in your hair for 2–3 minutes. This allows the bond-building ingredients to penetrate the hair shaft and provide repair and moisture.

For very dry or damaged hair, leaving it on slightly longer can provide additional conditioning.

Step 7: Rinse with Cool Water

Rinse thoroughly with cool or lukewarm water. Cooler water helps smooth the hair cuticle, which can make hair appear shinier and reduce frizz.

Optional: Follow with Additional Olaplex Treatments

For deeper repair, many people use these products alongside other treatments in the line, such as:

  • A pre-wash bond treatment

  • A leave-in repair cream

  • A bonding hair oil for shine and protection

Using a full routine can help maintain stronger, healthier hair over time.

Tips for Best Results

  • Use only a small amount because the formula is concentrated.

  • Focus shampoo on the scalp, conditioner on the ends.

  • Use 2–3 times per week or as needed depending on your hair type.

  • Pair with heat protection if you frequently style with hot tools.

Final Thoughts

Consistent use of Olaplex No.4 Shampoo and No.5 Conditioner can help improve the strength, softness, and manageability of damaged or chemically treated hair. By focusing on proper application and allowing the conditioner time to work, you can maximize the bond-repairing benefits and maintain healthier hair over time.

Digital Perm Vs. Wave Perm

Image
Even being a licensed hairstylist, I had no idea this digital perm concept even existed until finding it on Google and asking some other hairdressers about it. Apparently the digital perm makes it so that when you air dry your hair, your hair goes from slightly wavy to big and round. Exactly like if you were to curl your hair with a curling iron. Only most Asian salons will perform this service. They wrap your hair in some metal perm rods and then hook up this machine to the perm rods to heat them up while apply perm solution on the rods. A spiral perm or ordinary perm you can get at any salon is  like the photo on the right. It is wrapped with rods and then a perming solution is applied. You wait, and then rinse when it is done processing. This procedure causes your hair to have more frizz  and is more damaging than the digital perm.  But keep in mind that both perms are very damaging and not anyone can get one. If you have pre lightened hair (bleached/high...

Temporary, Semi, Demi, Permanent? What's the Difference?!

Image
I know a lot of people are confused on the subject of what is temporary? Semi-permanent? Didn't even know there was such thing as a demi-permanent? So, temporary dyes are, well, temporary. Temporary in the sense that they are one time use. Temporary dyes are anything from spray ins, such as the photo on the right, colored gels (the kind that comes out during Halloween season), and rinses. Apply the temporary coloring right over your own hair color (without bleaching or anything). When you wash your hair, the color comes out. Temporary cannot  lighten your hair. Semi-permanent Semi-permanent hair dyes are most likely the vibrants. Red, blues, orange, yellow, green, purple, teal, etc. Semi-permanents do not require a developer but they do require that your hair be bleached to show up vibrant. Take a white piece of paper and get a pink crayon, the color comes out pink. Take a black piece of paper and try to color it pink, and it doesn't show up. Same concept with your hair...

Review: Moroccan Oil

Image
What's all the hype about Moroccan Oil? Moroccan oil is basically a brand name form of argan oil. It is penetrating and your hair actually does benefit from it. It may be pricey, but it revives, strengthens, conditions, and reduces your blow dry time. It revives overprocessed, dry, brittle hair, and add shine and improves elasticity. Does not leave hair sticky or greasy (unless you use it wrong). They also have a LIGHT formula which is for blondes and very fine hair. To use Moroccan Oil, wash and condition your hair. Using a blow dryer, remove excess water from your hair until your hair is damp, but not dripping wet. Apply one pump of the oil into your hand and rub together. Apply it mid-shaft to ends and then blow dry completely. If you need more, add a dime size amount to your hands and run it through your ends only. Applying it to your scalp will make your hair greasy.
