How To Use Nizoral Shampoo

Wash Your Hair With Over-the-Counter Shampoo

1. Get your hair and scalp thoroughly steamed. You can either get into the tub or sit down in a sink or bathtub. You can then shampoo your hair as you would normally.

Depending on your preference, you can choose to use either warm or cold water.

If you have dandruff, an over-the-counter shampoo may be a good option.

2. Use enough shampoo to wash your hair. Use about 1 teaspoon (5mL) shampoo if you have thin or short hair or 1 tablespoon (15mL) if you have thick or lengthy hair. Apply the shampoo to your scalp by putting it in your palm.

Do not worry about the exact amount of shampoo you need. It doesn’t matter if you have a little less than you need. You can always add more shampoo to your hands if you have too much shampoo.

How To Use Nizoral Shampoo

3. Massage the shampoo with your fingertips. Massage your scalp with shampoo. This is the area the medicine should be focusing on. Use your fingertips to massage your scalp by moving them around in circular motions.

Next, apply the shampoo along the length of your hair. As you continue to press your fingertips on your scalp, work the shampoo into a lather. This should take no more than 15 seconds.

When you apply shampoo to your scalp, avoid scratching it with your nails. Use the tips of your fingers only.

You can add more shampoo to your hands if you find it challenging to create a lather.

4. Run water to rinse the shampoo from your hair. Apply the shampoo to your hair. Rinse the shampoo off with running water. For approximately 30 seconds, place your head in the running water.

5. Continue the process one more time. Use the same shampoo you used before, and then lather it on your scalp. Rinse your hair well to remove all shampoo.

To get full benefits, you only need to apply the treatment once.

After shampooing, apply the conditioner and dry your hair.

6. The shampoo can be used 3-4 times per week for 2 and 4 weeks. Nizoral over-the-counter is safe enough to be used on your hair and scalp up to four times per week for as long as four weeks. You can stop using shampoo if you notice dandruff. It should be used at least three times per week for at most 2 weeks.

  • Tip: Talk to your pharmacist or doctor if you have any questions about the recommended time to use Nizoral over the counter.

Applying Prescription-Strength Shampoo

1. To make your scalp damp, pour a little water on it. You can either take a shower, bath or sit down in a bathtub. You can shampoo your hair and scalp the same way you would normally.

Water can be used either warm or cold.

You may need a prescription-strength shampoo if you have a fungal infection on your scalp.

2. Use the shampoo on the scalp. Apply enough shampoo to cover the area. For short hair, use 1 teaspoon (5mL) and 1 tablespoon (15mL), respectively.

You can dispense more or less shampoo than you need. If you don’t have enough shampoo, you can add more or change the amount.

Applying Prescription-Strength Shampoo

3. Use your fingertips to work the shampoo into a creamy lather. Use your fingertips to massage the shampoo into your scalp. Next, move your fingers in small circles around the scalp. Continue this process until you have a foamy shampoo all over your scalp. Then, work the shampoo through your hair.

As you massage the shampoo into a lather, be careful not to scratch your scalp.

4. Allow the shampoo to sit on your scalp for five minutes. Let the shampoo sit for five minutes after you’ve finished lathering it. Nizoral, a broad-spectrum antifungal, helps prevent the growth of many fungal infections. The medicine will work best if left on your scalp for a while.

You can either set a timer or estimate how long it will leave the shampoo on your hair. You can leave the shampoo on your head for a little longer than recommended.

5. Use running water to rinse the shampoo out. Rinse your hair with warm water after the time has expired. Use warm or cool water. Continue to rinse your hair and scalp until all shampoo is gone.

If you wish, conditioner can be applied to your hair.

After using the best shampoo and conditioner, dry your hair and style it as you would normally.

Nizoral is a great way to clean your hair and scalp. It would help if you waited at least one day before shampooing your hair with another shampoo.
