15 Common Hair Care Mistakes That Are Ruining Your Hair (and How to Fix Them)

We all want healthy, shiny hair — but sometimes, without realizing it, we sabotage our strands with bad habits. From over-washing to using the wrong tools, these small missteps can lead to dryness, frizz, breakage, and slower growth over time.

The good news? Once you know what you’re doing wrong, you can make small changes that have a big impact. In this guide, we’ll walk through 15 common hair care mistakes, how they damage your hair, and the simple fixes to get your strands back to their healthiest state.

1. Washing Your Hair Too Often

Daily washing can strip away your hair’s natural oils, leaving it dry and brittle. Unless you have an oily scalp, 2–3 washes per week is plenty.
Fix: Use dry shampoo between washes to refresh your hair without stripping moisture.
Amazon Pick:
[Lasso: Dry Shampoo] — Absorbs oil, adds light volume, and leaves hair looking freshly washed.

2. Using Water That’s Too Hot

A steaming hot shower may feel amazing, but it can dry out your scalp and rough up the hair cuticle, leading to frizz.
Fix: Wash with lukewarm water and finish with a cool rinse to seal the cuticle.

3. Skipping Heat Protectant

Heat styling without a barrier is one of the fastest ways to damage your hair. High temperatures break down keratin, causing dryness and split ends.
Fix: Always apply a heat protectant before blow drying, curling, or straightening.
Amazon Pick:
[Lasso: Heat Protectant Spray] — Lightweight formula that shields up to 450°F without leaving residue.

4. Brushing Wet Hair with the Wrong Tool

Wet hair is more elastic and prone to snapping. Using a fine-tooth comb or stiff bristles can cause breakage.
Fix: Use a wide-tooth comb or a detangling brush designed for wet hair.
Amazon Pick:
[Lasso: Wide-Tooth Comb] — Gentle on wet strands, perfect for evenly distributing conditioner.

5. Overusing Hair Products

Too much styling cream, gel, or hairspray can cause buildup, weighing down your hair and clogging follicles.
Fix: Use a clarifying shampoo once a month to remove residue.
Amazon Pick:
[Lasso: Clarifying Shampoo] — Removes buildup while keeping hair soft and manageable.

6. Ignoring Your Scalp

Healthy hair starts with a healthy scalp. Neglecting scalp care can lead to dandruff, itchiness, and even hair thinning.
Fix: Exfoliate your scalp once a week and massage regularly to boost circulation.
Amazon Pick:
[Lasso: Scalp Massager Brush] — Stimulates blood flow and gently loosens buildup.

7. Sleeping on Rough Pillowcases

Cotton pillowcases cause friction, which can lead to frizz and breakage.
Fix: Switch to silk or satin pillowcases to protect your hair overnight.
Amazon Pick:
[Lasso: Satin Pillowcase Set] — Smooth, gentle, and great for both hair and skin.

8. Towel-Drying Too Aggressively

Rubbing your hair with a regular towel roughs up the cuticle and causes frizz.
Fix: Use a microfiber towel or an old cotton T-shirt to gently blot water out.
Amazon Pick:
[Lasso: Microfiber Hair Towel] — Super absorbent and gentle on delicate strands.

9. Overprocessing with Color and Chemicals

Frequent bleaching, perming, or relaxing weakens hair and causes breakage.
Fix: Space out treatments and use strengthening masks weekly.
Amazon Pick:
[Lasso: Deep Conditioning Hair Mask] — Repairs damage and restores softness after chemical treatments.

10. Skipping Regular Trims

Avoiding trims in an attempt to grow your hair can backfire — split ends just travel higher up the shaft.
Fix: Trim every 8–12 weeks to keep ends healthy.

11. Using the Wrong Brush for Your Hair Type

Different hair textures need different tools. A boar bristle brush is great for distributing oils in straight hair, but curly hair benefits more from wide-tooth combs.
Fix: Match your brush to your hair type and needs.

12. Pulling Hair Too Tight

Tight ponytails, buns, and braids put stress on the hairline and can cause breakage or even traction alopecia.
Fix: Opt for looser styles and use soft scrunchies instead of elastic bands.
Amazon Pick:
[Lasso: Silk Scrunchies] — Gentle on hair and reduce tension on the scalp.

13. Using Old or Dirty Hair Tools

Dirty brushes, combs, and heat tools can harbor bacteria and product buildup that transfers back to your hair.
Fix: Clean brushes weekly and wipe down heat tools regularly.

14. Skipping Conditioner

Even if your hair is fine or oily, conditioner is essential for maintaining moisture balance.
Fix: Apply conditioner from mid-length to ends to avoid weighing down the roots.

15. Expecting Overnight Results

Healthy hair is the result of consistent care over time. There’s no quick fix, but avoiding these mistakes will help you see gradual improvement.
Fix: Be patient and stick to a balanced routine.
