Quick answer: A good hair care routine for thinning hair is gentle and simple. Shampoo your scalp, condition the lengths, comb with a wide-tooth comb, keep heat low and wear styles that don't pull. A routine can protect the hair you have, but it can't fix the cause of thinning, so get checked if the loss is new, fast or patchy.
Thinning hair needs less fuss, not more. The aim of a daily routine is to stop extra breakage and pulling, so the hair you have stays on your head for as long as it can.
This checklist runs from morning to night. It's for anyone who has noticed their parting widening, their ponytail getting thinner or more hair in the plughole, and wants a routine they can stick to. Each step is based on published advice from dermatology bodies, linked as we go.
One honest point first. Hair care habits affect breakage and damage. They don't change the cause of most thinning, such as pattern hair loss, low iron or a recent illness. That part needs a proper look, which we cover near the end.
Morning checklist
1. Wash when your scalp needs it
There is no single right number of washes a week. The American Academy of Dermatology's tips for healthy hair say people with straight hair and an oily scalp may need to shampoo daily, while people with dry, curly or thick hair may only need to shampoo "at least once every 2 to 3 weeks as needed".
So go by your scalp. If it feels oily or itchy, or it flakes, wash more often. If your hair feels dry and brittle, wash less.
2. Shampoo the scalp, not the lengths
Put the shampoo on your scalp and massage it in with your fingertips. Don't scrub the lengths. The AAD's list of hair care habits that can damage your hair says to let the shampoo run through the lengths as you rinse.
3. Condition every time you shampoo
The same AAD page says to use conditioner after every shampoo. Where you put it depends on your hair:
Fine or straight hair: conditioner on the ends only, so the roots don't go flat.
Dry or curly hair: conditioner along the whole length.
If you have fine, thinning hair, a light conditioner on the ends is usually enough. Heavy products near the roots can make hair look flatter and thinner than it is.
4. Detangle with a wide-tooth comb
The AAD advises against brushing wet hair. Swap your brush for a wide-tooth comb and start at the ends, working up. The AAD advice is:
Thick or curly hair: comb it in the shower while the conditioner is still in.
Straight hair: let it dry a little first, then comb gently.
Never tug through a knot. Add a little more conditioner and ease it out.
5. Blot, don't rub
The AAD warns that "roughly rubbing your hair dry can cause damage". It suggests wrapping your hair in a towel (or an old cotton T-shirt) to soak up the water, then letting it air dry where you can.
6. Keep heat low and use it less
Blow dryers, straighteners and curling tongs all add wear. The AAD's advice is to air dry when you can, use the lowest heat setting, keep contact time short and aim to use hot tools about once a week or less. If you do use heat, put on a heat protectant product first.
A simple swap: let hair air dry most of the way, then finish on a low setting.
Daytime checklist
7. Choose styles that don't pull
Tight ponytails, buns, braids, cornrows and extensions can all cause traction alopecia (hair loss from constant pulling). The British Association of Dermatologists' traction alopecia leaflet says early cases can regrow once the tight styles stop, but long-standing traction "can cause permanent destruction of the hair follicle".
What to do day to day:
Tie hair back loosely, with covered bands made for hair (no bare elastic).
Move your parting and ponytail position now and then, so the same spot isn't under strain every day.
If a style hurts, stings or makes your scalp feel tight, it's too tight. The AAD page on hairstyles that pull says to change it straight away.
If you wear braids, the AAD suggests keeping them in for no longer than 6 to 8 weeks, and keeping them loose at the hairline.
If you wear a weave or extensions, the AAD suggests 2 or 3 months at most, then a break.
8. Go easy on hold products and chemical services
The AAD lists styling products with long-lasting hold among habits that can damage hair, and suggests picking a style that doesn't need them.
For colour, perms and relaxers, space out touch-ups and only have one chemical service at a time. If you need both, the AAD says to perm or relax first, then wait 2 weeks before colouring.
9. Cover your parting in strong sun
Thinner hair means more scalp is on show. The BAD's female pattern hair loss leaflet advises protecting thinning or bald areas from the sun with sunblock or a hat to prevent sunburn. A hat is the easy option on a bright day.
Evening checklist
10. Take hair down and let your scalp rest
Take out clips, bands and tight styles before bed. Don't sleep in a tight ponytail or bun. The AAD lists rollers worn to bed most of the time as one of the habits that can lead to traction hair loss.
11. Sleep on something smooth
If your hair tangles overnight, try a loose plait or a silk or satin scarf. The AAD names silk and satin scarves as gentler choices for hair coverings.
12. Brush only to style
You don't need 100 strokes a night. The AAD calls that a myth: "Hair never needs 100 brush strokes a day." Brush or comb only to style or detangle, and do it gently.
Food basics
Diet won't reverse genetic thinning. But the NHS hair loss page lists weight loss, iron deficiency, illness and stress among the causes of temporary hair loss.
Keep it simple. Eat regular meals with enough protein, and don't crash diet. If you have heavy periods, follow a vegan or vegetarian diet or feel tired all the time, ask your GP about checking your iron. Our guide to iron deficiency hair loss and ferritin explains what the blood test shows. Speak to your GP or pharmacist before taking iron supplements.
Once a month: check, don't count
Daily hair counting tends to make people more anxious. The NHS says it's normal to lose between 50 and 100 hairs a day. Our post on how much hair loss is normal covers this in more detail.
Instead, check once a month. The AAD suggests looking each month for broken hairs at the forehead, a receding hairline or bald patches where styles pull. Take a photo of your parting in the same light each month, so you can compare like with like.
When a routine isn't enough
A good routine protects the hair you have. It won't treat the reason it's thinning. See your GP if:
the hair loss is sudden, patchy or fast
your scalp is sore, red, scaly or itchy
you feel unwell, or the loss is affecting how you feel day to day
The NHS also advises seeing a GP before going to a commercial hair clinic, to get an idea of the cause. It's honest about treatment too: "No treatment is 100% effective."

Frequently asked questions
How often should I wash thinning hair?
As often as your scalp needs. An oily scalp may need a daily wash, while dry or curly hair may only need washing every week or two.
Should I stop using heat on thinning hair?
You don't have to stop, but use it less. The AAD suggests the lowest setting, short contact time and hot tools once a week or less, with a heat protectant first.
Can tight ponytails make thinning worse?
Yes. Constant pulling can cause traction alopecia, mostly at the hairline and sides. Early on it can recover once you switch to loose styles, but years of pulling can cause permanent loss.
Is it normal to see hair on my brush every day?
Yes. The NHS says losing 50 to 100 hairs a day is normal. Get checked if you're losing much more than usual, or you see patches or a widening parting.
